m0unds__ has quit IRC (Ping timeout: 245 seconds)
m0unds_ has joined #arpnetworks gizmoguy_: this will be timeline'd hopefully... http://seclists.org/oss-sec/2014/q3/649 ***: gizmoguy_ is now known as gizmoguy awyeah: I seem to be getting extremely inconsistent disk read speeds on my VPS... is that just the nature of shared environments? 65MB/sec one minute and then 300+ the next up_the_irons: shouldn't be like that brycec: awyeah: Which host machine? up_the_irons: there can be bottleneck times, but mostly the I/O should be consistent brycec: up_the_irons: rebuilding and raids?
(I assume not, or you probably would've mentioned it already) awyeah: let me check my panel
kvr07 brycec: Aww good old kvr07 awyeah: I've been around for a little while ;) brycec: I used to be on kvr07
Also being on a low-numbered kvr doesn't necessarily equate to age
just where there was capacity at the time awyeah: yep -: brycec moved up to kvr21 due to some Linux bugs brycec: specifically, high UDP load would panic my kvm proc awyeah: hah, lame brycec: It was very lame with my UDP OpenVPN
And old bug, fixed in newer kvm so hence my move up_the_irons: yeah it had to do with UDP fragments brycec: which reminds me, I need to re-up up_the_irons: documented virtio bug brycec: ^ up_the_irons: if your NIC never saw fragments, it would be OK, otherwise not mercutio: bryce: under heavy write load hard-disk raid can be like that brycec: mercutio: eh? mercutio: 65mb/sec one minute, then 300k/sec the next. brycec: mercutio: 301 Redirect to awyeah mercutio: it was probably ages ago
oh 16 minutes, not that ages ago :) brycec: lol mercutio: oh it was awyeah that said it
for some reason awyeah is so dark i can hardly read it, weechat and it's damn colours. RandalSchwartz: I think I'm on kvr07 too.
Nope. 05(!) brycec: mercutio: same. I keep meaning to change my colours RandalSchwartz: I think my machine uses vacuum tubes mercutio: i dunno if there's a way to make everyone the same colour easily, but that may be quickest path.
i don't think it's even doing the 256+ colour thing. m0unds: yea, everyone but ops is green on mine brycec: mercutio: /set weechat.color.chat_nick_colors 1 m0unds: ops are blue
text is all white BryceBot: That's what she said!! brycec: BryceBot: no BryceBot: Oh, okay... I'm sorry. 'text is all white' m0unds: silly bot RandalSchwartz: roses are red! awyeah: It's not a huge impact I don't think. I'm trying to troubleshoot some performance issues on apache+php+mysql brycec: your bot is silly! oh wait, you don't have one RandalSchwartz: that's what she said! mercutio: hmm
whoever sadi that's what she said i can't read now m0unds: haha, my bot is on another net. he wouldn't do well here awyeah: Google PageSpeed claims my server takes 19 seconds to respond.... I can't reproduce that. RandalSchwartz: roses on a piano are nice, but tulips on an organ are better. mercutio: i set 0 oops
oh now it's red for everyone's nicks. brycec: whee, everybody are green and red now mercutio: i just need an op to talk :) m0unds: merry xmas brycec: /op brycec
>.>
<.< mercutio: maybe i need to join something like #debian :) brycec: btw wechatters, if you haven't set /set weechat.look.prefix_same_nick "⤷" you don't know what you're missing m0unds: ..speaking of which, miracle on 34th street is on one of the HBOs brycec: *weechatters mercutio: no-one's talking in there awyeah: oh
hey
that's sweet
I'm going to set it to "--" I think mercutio: brycec: what's that do? brycec: Really helps when there are multiple same-colour nicks awyeah: yeah, that's the stuff brycec: mercutio: instead of your nick appearing under itself several times, it's that character awyeah: hey. someone do me a favor mercutio: "under itself?" awyeah: load http://new.ohioares10.org/ in your web browser. brycec: mercutio: https://dl.dropboxusercontent.com/u/3167967/screenshot_2014-09-24_14-38-19.png awyeah: Tell me if it's slow. m0unds: it was slow to resolve mercutio: oh mine does inverse already BryceBot: That's what she said!! m0unds: took close to 6 seconds before first byte mercutio: with as bad colours as you brycec: ditto what m0unds said RandalSchwartz: slow to load awyeah: gah. mercutio: it says waiting for ages
it's still waiting
once it starts it's fine awyeah: well, f*ck.
Good thing I'm not a professional sysadmin. twobithacker: do you play one on TV? brycec: And refreshing, it loads right up pretty much m0unds: haha RandalSchwartz: me neither awyeah: Really need to learn more about optimizing this stuff. RandalSchwartz: I just poke around until Neil is happy m0unds: yeah, same here
loaded instantly after it loaded once awyeah: hmm. RandalSchwartz: "Yes... your page caches well!"
weird. not just cache. I emptied cache, and it still loaded relatively fast
must be some bad DNS lookups brycec: awyeah: You can semi-weed out the Apache-side if you just run "php $script.php" and see how long that takes to run awyeah: hmmmmmm brycec: RandalSchwartz: more likely the connection keep-alive RandalSchwartz: No - I closed the window mercutio: awyeah: i think dns resolution being slow is partially because it has to lookup awyeah.net etc as well brycec: I wouldn't trust your browser to close the connection awyeah: oh hey good call. running it on the command line takes quite some time. brycec: I'm just using curl, so only one lookup
btw http://en.wikipedia.org/wiki/HTTP_persistent_connection) BryceBot: HTTP persistent connection :: HTTP persistent connection, also called HTTP keep-alive, or HTTP connection reuse, is the idea of using a single TCP connection to send and receive multiple HTTP requests/responses, as opposed to opening a new connection for every single request/response pair. The newer SPDY protocol uses the same idea and takes it further to allow multiple concurrent requests/responses to be multiplexed over a single connection. RandalSchwartz: woo hoo. ugly calendar! mercutio: oh it's beign slow again brycec: awyeah: Is this your own code? or something like wordpress, joomla, etc? mercutio: tests with curl awyeah: joomla. brycec: Also, static resources should load (http) pretty quick
obligatory: ewww Joomla mercutio: curl -v > /dev/null 0.00s user 0.00s system 0% cpu 23.300 total m0unds: hahaha mercutio: not sure why it removed the url
23.3 seconds is pretty damn slow, that is to the public service link brycec: lol
Yeah, pulling up static resources like CSS is instantaneous
so your Joomla is slow awyeah: yeah brycec: perhaps your database is slow RandalSchwartz: that's what she said mercutio: 8.5 seconds the second time
it was going faster before awyeah: yeah I've been looking at DB stuff
that's where I'm the least knowledgeable, TBH brycec: @google slow joomla :P awyeah: but hooray, my mysql slow-query log is filling up brycec: You're probably looking at some mysql tuning RandalSchwartz: or upgrade to an actual database brycec: mysql isn't know for being a lightweight, and in a constrained VPS you're going to have some fine tuning to do
Also, Apache tends to be a resource (esp. memory) hog so see if you can ditch that mercutio: joomla is crap BryceBot: That's what she said!! mercutio: joomla can also leak
are you swapping? BryceBot: That's what she said!! RandalSchwartz: heh brycec: (I really, really dislike Joomla. But I was trying to remain constructive :P) mercutio: it says you're using apache awyeah: freebsd is always swapping. mercutio: if you're not using mod cgi type php... then you probably want to reduce max number of requests per process
to keep the memory consumption down.
you're always swapping? BryceBot: That's what she said!! mercutio: reduce minspare and maxspare too
it's much cheaper to create a new process than to swap awyeah: my php is an apache module brycec: freebsd doesn't normally swap... And this is coming from a guy who runs a storage ZFS server mercutio: bryce: it's not uncommon for joomla to use 250 mb of memory :) awyeah: You sure? I thought FreeBSD is always putting idle pages into swap. mercutio: per process..
awyeah: nah that's linux brycec: mercutio: I'm sure mercutio: freebsd is pretty slack about swapping brycec: I used to admin a few Joomla sites
well not the sites, other sites..., but there were joomla sites on the same server awyeah: I have 673/1500MB in use, and 419MB of swap in use. weird. m0unds: wait, you're using mod_php? mercutio: awyeah: you may have had a burst of processes before. did you restart apache? awyeah: yeah not doing fastcgi or anything.
yeah restarted it like 10 mins ago for a quick config change m0unds: you might wanna consider trying it; mod php is expensive mercutio: mod_php does suck yes. awyeah: well hold on here though, I get a ton of slowness when I run "php index.php" - huge delay. mercutio: esp when dealing with joomla etc.
awyeah: i use strace to debug those things :) awyeah: moving to fpm or whatever is on my list, but it sounds like maybe that's not the big issue right now. brycec: ^ correct mercutio: it makes it reasonably easy to see if it's doing something like db connect or such
ktrace on freebsd i think awyeah: hmmmmm mercutio: i think it's ktrace/kdump on freebsd. awyeah: Is there a "get started with ktrace in 10 minutes" type tutorial I could look at? m0unds: brycec: i like your prefix_same_nick char better than my ghetto arrow. thx for that. mercutio: well ti's annoying compared to strace for "spotting"
as you don't see the delay so easily
but it might mark seconds brycec: awyeah: for shits and giggles, reboot (fresh memory slate), stop apache (or it will eat up ram), and then run your php
m0unds: don't thank me, thank http://benoliver999.com/2014/02/18/weechatconf.html mercutio: you basically just run it and look at output briefly
and if something pops out at you it pops out m0unds: i was using --> awyeah: okay. I'll reboot. brb. m0unds: that one is fancier mercutio: it's a good exercise in not reading every line brycec: m0unds: I liked the idea of putting my buffers on top too :D
And I'm also doing the auto-hide quiet buffers ***: awyeah has quit IRC (Quit: ZNC - http://znc.in) m0unds: huh, i'm gonna have to check this out
i just made weechat as much like irssi as possible, but i'm down to try new stuff
haha brycec: m0unds: Mine looks like this now https://dl.dropboxusercontent.com/u/3167967/screenshot_2014-09-23_10-02-39.png m0unds: snazzy brycec: Actually it's a bit narrower than that screenshot
because it can me now :D
*can be ***: awyeah has joined #arpnetworks brycec: wb awyeah
awyeah: so now you're on a clean slate. The first query/run will be slow since it has to all come from disk, subsequent runs should be a bit faster awyeah: alrighty
stand by please. -: brycec sits anyways
brycec is a rebel awyeah: yep both pretty slow still
first and second brycec: Okay, so you've got a good idea where to tweak then
btw awyeah what are the vps specs? awyeah: 1.5GB RAM, 2x20GB disks brycec: Well that's not bad then
With that much ram, you should have no trouble fitting mysql in ram (caching, etc)
And frankly I'm surprised you're having as much trouble as you are awyeah: I wouldn't put it past myself to really screw things up ;) brycec: I'm blaming Joomla for now, both itself and whatever plugins etc have been configured awyeah: wordpress is relatively slow as well
check out http://www.ccskywarn.org
same server, same db server, but wordpress.
actually it's definitely faster on the command line for that site.
See, I evaluated joomla and drupal for this new site.
And ended up liking joomla... so... crap brycec: Oh so the CMS was your pick? awyeah: yep brycec: Might I recommend Concrete5 for a relatively lightweight gooey CMS? awyeah: concrete5, eh brycec: I've messed with it a bit in the past
Not doing any CMS nowadays
Or I do 100% static awyeah: Yeah, I need WYSIWYG editors, access control, etc brycec: Been burned by CMS vulnerabilities/hacks too many times awyeah: this site is going to have several people, each can only edit certain parts of the site brycec: c5 should fit the bill awyeah: one requirement is this
I need a nice calendar plugin.
And that calendar plugin needs to be able to automatically sync external ical feeds.
And it needs to provide its own ical feeds. brycec: awyeah: http://www.concrete5.org/marketplace/addons/-/view/?submit_search=1&search_keywords=calendar&sort=recommended&endorsed=endorsed
several of those do just that
Some are even free :p awyeah: Interesting. brycec: I like that the addons site even showcases sites using a given plugin
eg http://www.myactivechild.com/calendar/ awyeah: hmm
wow, Joomla has a lot of crap in it by default.
extensions and stuff brycec: Joomla is a lot of crap :P awyeah: I mean, I can't believe that something as popular as Joomla can be so crappy.
It's got to be somethign on my side here. m0unds: popular doesn't necessarily mean "good" :) awyeah: oh wow holy crap BryceBot: That's what she said!! awyeah: I changed to the default template
WAY faster brycec: sweet
Oh yeah that is fast m0unds: yeah, that loaded much faster
all the pages load right away -: brycec mashes the Bigger button brycec: twss BryceBot: Okay! twss! '
ACTION mashes the Bigger button
' awyeah: lol now I can't change it back, bleh
wow, I can't believe what a difference that makes, holy cripes. brycec: I was impressed as well mercutio: so how did joomla tuning go?
i suppose i should say awyeah because it's been a while brycec: mercutio: The resource hog turned out to be the theme he was using
switched to the default and it came up in <2s m0unds: yeah, weird how much faster it was mercutio: maybe it's going over some cache value or something
query cache size, or memcached limit or some other cache thingy m0unds: i've been messing w/ghost a bit. it's pretty nice for a blogging platform. don't really know what to think of node though brycec: m0unds: Link? (because googling "ghost node" was next to useless) m0unds: http://ghost.org brycec: So it's hoted? m0unds: https://ghost.org/download/ brycec: *hosted
Ah m0unds: i'm running node behind nginx
and just keep the app running w/forever (npm install forever -g) -: staticsafe just uses wordpress :)
brycec just doesn't blog m0unds: i just like playing with stuff
ran wp for years, ran octopress for a bit but updating it was a pita, so i never updated staticsafe: yeah i actually switched to octopress, then killed it and started brand new with WP up_the_irons: i like octopress m0unds: yeah, it's nice, but i'm lazy and having to write in vim then regen then deploy was just too much effort ;)
i did like having the blog's code and stuff living in a mercurial repo though, just clone it locally and commit new posts or whatever up_the_irons: yeah, for me, i like writing in vim, so that was a big plus ***: forgotten has quit IRC (Quit: leaving)
