well with ecc ram support
i was surprised how fast my new i7 was :)
and e3s are often faster than e5s
unless you want to spend a lot of money.. e3 has higher clock rate than e5.. you need a very parallel work load for e5
that said... i5 versus i7 often shows similar speed in lots of things ***: CaZe_ has joined #arpnetworks

how do you mean manually assign it? brycec: ifconfig eth0 ...

mercutio: freenode splits all the time brycec: does
FreeNode is a very large and popular target for DOS attacks, and when a node becomes sufficiently inundated and lagged, it disconnects from the network, hence a netsplit.

up_the_irons: raw cpu isn't always the bottleneck on servers
up_the_irons: e5 also has some low latency stuff for i/o interconnects, and supports more ram, and quad channel memory
like if you want to go above 32gb of ram...
http://www.intel.com/content/www/us/en/io/direct-data-i-o.html
also if you pay "per cpu" a lot of money for licensing you can get really fast really expensive e5s up_the_irons: mercutio: yeah makes sense mercutio: lots of people want to save money, but if you get e5-2620*2 on one server versus two e3-1270v2 servers, it's probably similar cost
e5 has 12 cores with hyperthreading, two 3s have 8 cores with hyperthreading
but e3 is like 3.4ghz and e5 is like 2.1 ghz
hmm 2 ghz burst to 2.5 ***: hive-mind has quit IRC (Ping timeout: 255 seconds) mercutio: versus 3.5 ghz burst to 3.9 ghz
but if you're not doing highly parallel applications, single thread performance is better on e3

cos they don't want to risk instability :) up_the_irons: yep
we got the RFO for that. It was a multicast flood. Supposedly, _now_ they inserted a rate limit and ACL for multicast. mercutio: joy
the thing is they have lots of peering exchanges!
so they don't relaly have an excuse
sometimes i'm surprised the internet works as well as it does tooth: s/some/many/ brycec: I find the Internet works about the same as driving - It's mostly sheer luck and self-preservation.
(that there aren't more accidents) mercutio: brycec: heh
i think it's funny when china manages to somehow take a whole lot of US routes brycec: "somehow" tooth: That's not the only case really. mercutio: a lot of problems come from least cost routing tooth: one year at defcon the network peeople routed everything out through new york via bgp (from vegas) mercutio: there's no in built distance / best path stuff
there's just a list of whose network it goes through
so if you advertise someone elses ip addresses as directly connected then that can take precedence over someone else who's learned through someone else brycec: yep ***: hive-mind has joined #arpnetworks

CESSMASTER has joined #arpnetworks
HighJinx has joined #arpnetworks CESSMASTER: I ran into a weird problem on a freshly-reimaged fbsd 9.0 VPS. 'portsnap fetch' failed, complaining that it could not create the relevant files in /var/db/portsnap/snap. After the failure, there were exactly 11999 files in that directory. I could create a new file in it with touch, but (for example) vi would fail to start because it couldn't create temp files. I rm -rf'ed /var/db/portsnap/* and /usr/ports, and then portsnap fetch
completed without issue
has anyone seen something like that before? I forgot to df -i before I deleted those directories staticsafe: CESSMASTER: how big is your disk? CESSMASTER: 5G
df reported it was 50% full staticsafe: ah yes
you ran out of inodes most likely CESSMASTER: and 'touch' doesn't actually use an inode if the file remains empty? staticsafe: hmm CESSMASTER: i mean, the fact that it crapped out with 11999 files in that directory makes it look like some kind of weird per-dir limit, except i was trying to run vi on /etc/portsnap.conf so presumably the temp file would be created in a totally different dir mercutio: what static said
there have been issues in the past with freebsd default inodes 5gb and ports CESSMASTER: i guess the UFS guys don't care about such small partitions too much ***: hive-mind has quit IRC (Ping timeout: 248 seconds)
