SMF Support > Server Performance and Configuration

Sudden forum slow down...

(1/3) > >>

Hey all,

My SWF forum at http://www.speedshots.net/tvwdra/forum/ [nofollow] has gotten slow over about the past two weeks. It's been up and running fine for a few months now.

I've optimized the tables, checked for errors (none), and upgraded to version 1.0.5, but the problem still occurs.

The intial page load is quite slow, and transitions to boards/topics are slow too.

I haven't changed any admin or server options recently. I get the same behavior w/the default theme. The site is not very large, I have not config'd any of the performance reducing features like "check avatar size...", and no mods are installed.

Forum version: SMF 1.0.5
PHP version: 4.3.10
MySQL version: 4.0.17-standard
Server version: Apache/1.3.33 (Unix) mod_ssl/2.8.22 OpenSSL/0.9.7a PHP/4.3.10 mod_perl/1.29 FrontPage/5.0.2.2510
GD version: bundled (2.0.28 compatible)

I've uploaded the status script, which can be found at http://www.speedshots.net/tvwdra/forum/status.php [nofollow]

Any help or ideas would be greatly appreciated.

Thanks!

yes, I think that it's some sort of bug.  After I got a certain number of posts on my forum, it immediately slowed down so it took at least 10 seconds to load each page instead of just 1 second.  Maybe just set your server to automatically reboot every five minutes.  That's what I did.es 01

Weird I am administrating a forum with 50K users and I have no slowdowns :) Tell your host to enable table_cache and set it to a bigger value like 512, it will solve most of the speed issues ;)

Grudge:
That is slow. I can't believe it can be taking that long to generate those pages though - can you switch on the page generation times so you can see how long SMF is actually taking to generate the page? You haven't changed any settings recently (For example the dreaded "Check avatar sizes every page load") Are you on shared hosting?

Umm, what?  This forum and many other forums have more than 500 posts (which is what that forum has) and none of them are slow.  I'd guess your problems were server related or caused by modifications or themes.  Or were you the one running a server with 32 megs of ram?

Your server isn't well configured, but that's no surprise.

This URL is almost instant:
http://www.speedshots.net/tvwdra/forum/index.php?theme=2

This is very slow:
http://www.speedshots.net/tvwdra/forum/index.php?theme=1

But this is fast:
http://www.speedshots.net/tvwdra/forum/index.php?theme=800

They all show exactly the same thing.  Something strange is going on here for sure.
