Hien: i don't remember tbh.
Hien: was quite a while ago ***: lazard has quit IRC (Ping timeout: 264 seconds) up_the_irons: whitefang: the load on the server is normal whitefang: how is CPU time allocated?
it seems a bit better now, but only have 3 of the 5 people that were on it from earlier. up until about 20 minutes ago with 5 people it was brutally painful all night.
it does seem much better now. up_the_irons: CPU time is scheduled by the standard Linux scheduler jbergstroem: standard. that's deadline, right?
or is it cfq nowadays whitefang: yah now its really bad once the 4th person connections
up_the_irons: kvr14 still normal cpu? up_the_irons: whitefang: yes
jbergstroem: i think it's deadline ***: Ehtyar has quit IRC (Quit: Don't follow me) up_the_irons: Hien: making your vps now Hien: up_the_irons: nice, just recieved billing email ;) up_the_irons: :) Hien: i just ssh'd

QinQ (802.1AD) slvan(4) works great .. if you set the right mtu
1500 mtu on em0 .. 1496 mtu on svlan5 .. and stuff like nfs mounts of -r=16384,-r=16384 "just work(tm)"
between arpnetworks vps'es of course jbergstroem: mosh is just awesome when you have anything above 300ms latency whitefang: ehhhh. that's weird. one of my processes was "Killed" but not by me.

HighJinx has quit IRC (Ping timeout: 252 seconds) up_the_irons: toddf: if I had the time, i'd pick your brain on that and write up a full blog post. definitely interesting stuff and probably not a whole lot has already been written on it.
dr_jkl: <3 :)
mercutio: how's your routing doing? ***: HighJinx has joined #arpnetworks toddf: up_the_irons: in theory the mtu of em0 should permit svlan to go 1500 by adding 4 more bytes, but I'm guessing there is somewhere outside kvm that is blocking it from being larger than 1500, but at least I figured out why nfs wasn't working
$ cat /etc/hostname.svlan5
vlandev em0 -autoconfprivacy mtu 1496

10.1.4.2:/u /u nfs rw,nodev,nosuid,intr,-3,-r=16384,-w=16384,-b 0 0 up_the_irons: we are announcing 174.136.96.0/20 out of NTT again. I'll be around if there are any issues. I've tested one of our own /24 for over 24 hours and things seem good.
toddf: yeah there's MTU stuff all over. if i had the patience, we could probably make it work. ***: Lucifer7 has quit IRC (Read error: Operation timed out)
