LLKCKfan has joined #arpnetworks LLKCKfan: I was wanting to know if there is a way to find out why my computer is acting like it is on dailup when I am on cable and getting my full speed mercutio: that's a very open ended question
is dns resolution slow?
is it windows or linux or os x or what
basically i'd check ping first, then check dns, then check cpu usage, then check hard-disk performance LLKCKfan: cdablre
It is cable
windows
ping is 0 brycec: Also what does this have to do with ARP Networks? ***: Invader has joined #arpnetworks

gcw|mbpro has quit IRC (Ping timeout: 250 seconds) LLKCKfan: Hello ***: r0ni has quit IRC (Quit: Textual IRC Client: www.textualapp.com) brycec: yeah mercutio, my thoughts exactly. mercutio: i've been playing with zfs on ssd
is that general interest?
it's still slower than btrfs or ext4 for read speeds :( brycec: Under what OS? mercutio: linux
i got 3x samsung evo 840 brycec: So could just be the Linux ZFS implementation :P mercutio: could be brycec: (Fuse, right?) mercutio: nope
it went past fuse ages ago brycec: ah mercutio: i'm at about 1.2 gigabytes/sec though
and i got it up to 1.4 gigabytse/sec before
but ext4/btrfs on mdadm or on btrfs raid got up to 1.5 to 1.6gb/sec read speed brycec: That seems faster than the bus should handle. mercutio: bus should handle 2 gigabytes/sec
minus overheads brycec: @wa 6gbps to gb/s BryceBot: convert 6 Gb/s (gigabits per second) to gigabytes per second;0.75 GB/s (gigabytes per second);6×10^9 b/s (bits per second);750 MB/s (megabytes per second);= SATA revision 3.0 speed ( 6 Gb/s );~~ 1.2 × OC96 speed ( 4.977×10^9 b/s );~~ 1.2 × USB 3.0 speed ( 4800 Mb/s );information rate;[time]^(-1) [information];Time to transfer 1 gigabyte:, ->1.3 seconds, ->0.022 minutes;Time to transfer 1 terabyte:, ->1333 seconds, ->22 minutes brycec: ^ mercutio: this is 3 ssd's
each on 6 gigabit ports brycec: Ahhh so 3*.75GB/s mercutio: each ssd can do 500mb/sec+ on it's own brycec: *its :p mercutio: it's hard to benchmark though
being evos they have fast write at the beginning but not after writing more data brycec: So secure erase every time? mercutio: but in real world access you're not likely to write more than the fast speed often aynway
nah i'm not doing anything liek taht :/
i was mostly concerned about read speed aynway brycec: heh mercutio: but then i decided to compare linux kernel compile time brycec: I've done that before :) mercutio: and other such things
curiously lz4 is faster than non lz4
even on amazingly fast ssd's
doing 100% cpu
but basically zfs is slightly slower brycec: 19s was my record (lvm mirror with 2 SATA3 SSDs that max at 500-600 read, -j12) mercutio: but < 1 % with lz4 compression
and just over 1% without lz4 compression
19s to do what exactly? brycec: make defconfig && make mercutio: wow
what cpu speed was that?
my kernel compile times went up at some point brycec: Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz
and 16Gb mercutio: but it's like 2:07 for zfs brycec: *16GB RAM mercutio: what
i'm on i7-4770
what does defconfig enable?
i'm using my standard kernel
i used to be just under 2 minutes
but yeh if it's minor difference it doesn't really matter
and lz4 uses up less space :) brycec: No idea really... Just "defaults" as determined by Linus and firends. mercutio: and it seems raidz gives good enough performance brycec: *friends mercutio: so i don't really need to use raid 10
because most things on linux don't do parallel i/o
and raid10 doesn't really speed up serial i/o
it just means that it doesn't slow down as much when doing parallel i/o
but ssd's don't really slow down that much with parallel i/o anytway
maybe it was an old kernel
i used to have 15 minute compile times on a 486 i think brycec: Wow really? My 486DX2 took 2 hours mercutio: maybe i was imaginging things brycec: (compiling some old 2.2 kernel, IDE drive...) mercutio: weird
oh maybe it was 40 minutes, and then 15 minutes when i
oh hangon
this was 2.1 kernel
like 2.1.110
so that looks like crica 98 brycec: My 486 died when I moved :( mercutio: damn
i going to see if it still compiles :/
it's not much gbigigger than current patches :/ brycec: Good luck :) mercutio: Makefile:160: arch/x86_64/Makefile: No such file or directory
ho hmm
% ls -l arch/
alpha/ arm/ i386/ m68k/ mips/ ppc/ sparc/ sparc64/
i need a 32 bit distro m0unds: i'm so used to using x64 arch that when i had to reimage something with a 32-bit cpu, i didn't have a compatible image for it mercutio: i found some old distribution
i'm hoping i can extract binaries from it :) m0unds: haha, good luck mercutio: bin/zsh: Linux/i386 demand-paged executable (QMAGIC)
doesn't seem to want to chroot and run that :/
i assume that's a.out ***: TheHiTCHO has quit IRC (Remote host closed the connection)
