| <mitsuhiko> Yann2: jep :D | |
| <Mirv> Yann2: just in theory, in case it seems it takes months for Canonical to really fix / get up to speed the LoCoTeam servers, how's the situation with ubuntu-eu's server (speed/space), and is it welcoming new LoCoTeams? | |
| <Mirv> I'd really think Canonical will fix the problems, but people have been a bit annoyed for some time already because of the slowness problems, and I still don't know any ETAs or such | |
| <Yann2> Mirv > we actually don't welcome new teams, as the cpu usage is growing _fast_ | |
| <Yann2> Mirv > but anyway, we'll never achieve to get an as good uptime as a company like canonical :) | |
| *** jalrnc_ is now known as jalrnc | |
| <Mirv> Yann2: yeah, I was just curious. good to know that also you have increasing amount of users :) | |
| <Mirv> a common "problem" in the Ubuntu world... | |
| <Yann2> I think our moinmoin is killing us, if we could optimize this we may have room for others again :) | |
| <Mirv> big response times all in all are killing our server | |
| <Mirv> requests go into a queue and then more lag occurs and more requests go into queue | |
| <Mirv> there wouldn't probably be a problem if edgy was not just released... Canonical people have probably enough work anyway, and of course part of them are probably even resting... | |
| <Mirv> but it's now again today a bit better than it was yesterday, so maybe we can handle a little more wait | |
| <Yann2> :) | |
| <Yann2> the whole games is to find the bottlenecks :) | |
| <JanC> moinmoin is filesystem-based... | |
| <Yann2> that doesn't mean it has to be so slow :) | |
| <Yann2> dokuwiki is filesystem based too ;) | |
| <Yann2> JanC , what wiki are you using? | |
| <JanC> the main ubuntu wiki | |
| <Yann2> that's moinmoin :) | |
| <JanC> I know | |
| <JanC> choosing another filesystem or tuning the existing one might help... | |
| <JanC> it will probably also mean a higher data loss risk ;) | |
| <Yann2> I think there are one or 2 functions from this wiki, that make it a lot slower, and that might not be needed | |
| <JanC> what caching headers do you / does it use ? | |
| <Yann2> ? | |
| <JanC> telling browsers to cache pages for some (longer) time might help | |
| <Yann2> yup | |
| <JanC> it's just a bit annoying for editors maybe | |
| <Yann2> may also cause consistency problems :) | |
| <Yann2> yep | |
| <JanC> an intelligent server-side cache might help too | |
| <Yann2> oh.. we tried :/ | |
| <Yann2> it was such a pain | |
| <Yann2> (squid) | |
| <JanC> if moinmoin can be teached to invalidate pages that have been changed | |
| <JanC> I mean something intelligent and using in-memory caching | |
| <Yann2> i'm not a python expert... ubuntu-de is using moin, i don't :) | |
| <JanC> does the server have enough RAM free? | |
| <Yann2> >2GB cache | |
| <Yann2> Mirv > you're ubuntu-fi right? i don't find it that slow :) | |
| <Mirv> Yann2: it's better today.. during the last week it's often been so that there are 20-40s load times for a page | |
| <Mirv> and yes, ubuntu-fi .) | |
| <Yann2> :) | |
| <Yann2> what teams are on this loco server? | |
| <Mirv> well, I'm not sure.. but newz2000 has said that we are the ones that are really getting that server hammered, so I guess we are the largest one and the others are some smaller (IT-wise) countries | |
| <Mirv> and there was this complete blackout when they had this great idea of moving also Ubuntu Italy to the same server -> total downtime of ca. 15 hours :) | |
| <Yann2> \o/ :D | |
| <Yann2> downtimes happen :) | |
| <Yann2> 15 hours isn't even that bad ;) | |
| <Yann2> imagine, hmm, your motherboard dies :D | |
| <JanC> we don't really have load problems for Belgium, as all languages spoken here are "foreign" languages (as in: there is a large(r) community of speakers outside Belgium, and people use the respective forums etc.) | |
| <Yann2> oh, JanC , are you the new -be locoteam leader? | |
| <Yann2> s/leader/contact | |
| <JanC> I'm the team contact, not the team leader :) | |
| <Yann2> hey, congrats :) | |
| <JanC> btw: if you have > 2 GiB RAM, it should be possible to just keep the whole wiki in RAM and still have plenty of free memory :P | |
| <Yann2> and hoping it'll never reboot :) | |
| <JanC> but I guess the problem is that pages get rendered every page view again | |
| <Yann2> i don't know moinmoin | |
| <Yann2> jalrnc is our new moinmoin expert :] | |
| <JanC> no, I mean caching the rendered version of the last revision | |
| <JanC> but I don't know moinmoin and if that's possible | |
| <JanC> :) | |
| <Yann2> i think there already is caching :) | |
| <JanC> if you have (good) caching there shouldn't be a problem with something like a wiki IMHO | |
| <JanC> it's not like all pages change every minute or so | |
| <Yann2> page rendering is not necessarily the pages that cause the wiki to be slow | |
| <JanC> if you have a forum that might be the culprit too | |
| <Yann2> on dokuwiki, the heaviest pages were rss feed and last changes pages | |
| <Yann2> nope the forums are ok | |
| <JanC> rss feeds are sometimes hammered by idiots that check them every minute or so | |
| <Yann2> in dokuwiki it just was poorly coded with a dumb utf8encode clone function | |
| <Yann2> and that function in the rss feed caused the whole server to become damn slow :) | |
| <JanC> on a site of a non-profit that I work for, we generate static rss feeds when articles get added to the site | |
| <JanC> (added or removed or changed in fact) | |

| *** yama_away is now known as yama | |
| <Yann2> yup | |
| <Yann2> but this whole performance tuning need involving in the core of the script we uses... and that needs a LOT of time :) | |
