| foo | Er, someone is telling me how debian 2.6.8 is better than ubuntu 2.6.16. | 04:08 |
|---|---|---|
| foo | He is telling me to try a 2.6.8 kernel on ubuntu | 04:08 |
| infinity | I wouldn't recommend it. | 04:16 |
| foo | eh, yeah, we're not going to do that. | 04:16 |
| infinity | OTOH, we've never had a stable release with 2.6.16 either. | 04:16 |
| foo | I know there will be some issues with udev, I think. | 04:16 |
| infinity | breezy = 2.6.12, dapper = 2.6.15, edgy = 2.6.17, feisty = 2.6.20 (when it's out) | 04:17 |
| foo | eh, I'm just having some issues. Everyone says it's IO, but the data center doesn't accept that answer. | 04:18 |
| foo | This server pushes 100mbit .. and the iowait from iostat increases.. | 04:18 |
| foo | Load ranges from .1 to 350 | 04:18 |
| infinity | What does it serve? | 04:29 |
| foo | files with apache, mainly. | 04:29 |
| foo | Well, only. | 04:29 |
| infinity | Static, or dynamic? | 04:29 |
| foo | dynamic | 04:29 |
| foo | lots of file uploading/downloading | 04:29 |
| foo | 100mbit cap | 04:29 |
| infinity | DB backend? | 04:29 |
| infinity | PHP, Perl, Python? | 04:29 |
| infinity | It's entirely possible you just allow too many client connections. | 04:30 |
| infinity | Alternately (and this one sounds weird until you think about it), you may be running too few apache instances, not too many. | 04:30 |
| infinity | It's very costly for apache to fork new children when the hit count increases. Very. | 04:30 |
| infinity | If you start with more MinSpares, it goes more smoothly. | 04:30 |
| foo | PHP | 04:31 |
| foo | Hm. infinity, should I check for connections about netstat or something? | 04:31 |
| foo | I've had several guys look at this ... everyone is blaming IO | 04:31 |
| infinity | When the load is huge, "ps ax | grep apache" and see how many are running. | 04:31 |
| foo | But how could a network cap at 100mbit cause IO on a server.. I'd expect it to read/write with that | 04:31 |
| infinity | If there's several hundred, or something, then you really want to bump up MinSpares in the config, or limit MaxClients. Pick one. Either will help. | 04:32 |
| foo | Apache has already been optimized, but. hm | 04:32 |
| infinity | Err, when people blame "I/O", they're not blaming the network, they're blaming slow disk and such. | 04:32 |
| foo | # netstat -nap|grep -c ESTA | 04:33 |
| foo | 381 | 04:33 |
| foo | yeah, I know | 04:33 |
| foo | I just don't get how a server pushing 100mbit could have IO | 04:33 |
| foo | issues | 04:33 |
| infinity | Why not? | 04:33 |
| infinity | It's not about raw disk throughput, it's about crazy random access. | 04:33 |
| foo | heh, that might be what it is | 04:33 |
| foo | That's what I'm thinking | 04:33 |
| infinity | But in my experience with PHP/Apache, I'd suspect you're CPU bound on apache forking. | 04:34 |
| foo | 192 requests currently being processed, 20 idle workers | 04:34 |
| foo | load is 1.25 right now | 04:34 |
| foo | Pushing 81mbit right now | 04:34 |
| infinity | grep SpareServers /etc/apache2/apache2.conf | 04:35 |
| foo | MinSpareServers 20 | 04:35 |
| foo | MaxSpareServers 27 | 04:35 |
| foo | worker and prefork, probably | 04:35 |
| infinity | No, those are both for prefork. | 04:35 |
| foo | oh, ok | 04:35 |
| infinity | Min is the number started at startup as spares, Max is the number it will keep idle once connections die off. | 04:36 |
| foo | ok | 04:36 |
| infinity | For your sort of load, you might want something more insane like Min 50, Max 75 | 04:36 |
| infinity | Or even higher. | 04:36 |
| infinity | If you're doing 200 requests right now. | 04:36 |
| infinity | Min 100, Max 150. | 04:36 |
| infinity | Experiment, have fun. :) | 04:36 |
| infinity | If you have the RAM to back up that sort of thing anyway, which you better if you're trying to saturate 100Mbit. | 04:37 |
| foo | Hm, 1GB RAM | 04:38 |
| foo | infinity: FYI, I've been playing around for weeks now. I've pretty much had it. | 04:39 |
| infinity | Is that PHP serving content from a DB? | 04:40 |
| infinity | If so, tuning said DB enging for that sort of load is just as important as tuning Apache. | 04:40 |
| infinity | s/enging/engine/ | 04:41 |
| foo | Nope, not from DB | 04:42 |
| infinity | Kay. | 04:42 |

| ArwynH | lo | 04:59 |
| ArwynH | just wondering, is there any plans to implement a server control panel of sorts? | 05:00 |
| ArwynH | If so, can I have a link to the spec please? Or should I write one myself? | 05:01 |
| levander | ArwynH: there are already some of those written that are free software, like cpanel | 05:54 |
| foo | ArwynH: Look into webmin | 05:55 |
| ArwynH | foo: webmin is a nightmare and is not in repos. | 06:17 |
| foo | ArwynH: Nightmare? Why? Yeah, isn't in repos. | 06:17 |
| ArwynH | foo: it isn't in the repos because the code is a nightmare to maintain. I've tried running it before. | 06:18 |
| ArwynH | it's a pain to run aswell | 06:19 |
| ArwynH | anyway, a web interface isn't what I'm looking for. | 06:19 |
| foo | I see | 06:19 |
| ArwynH | I've pretty much decided what I want and I havn't found anything like it in the oss world, so It looks like I'll have to write it myself, but I'm just trying to make sure. | 06:21 |
| foo | ah | 06:21 |
| levander | ArwynH: maybe write a spec first and circulate, maybe people will help you based on the spec? | 06:25 |
| ArwynH | levander: i plan to. hence me checking if there was one available to look at first. | 06:25 |
| levander | ArwynH: maybe circulate it on webmin and cpanel mailing lists, after written? | 06:26 |
