Hello,


I was using phpbb at old times, but engine is far too much boring for me and i went on SMF, it was great but some problems appeared, then i took one dedicated server which slows kinda at 20~30 concurrent connections.

Here is the status.php:

I'm using the following:
Apache 2 & PHP 5
MyISAM tables storage
SMF (lastest stable version: 2.0.2)
SimpleBoardPortal (Shoutbox activated and only visible on index and not shown by guests, 5sec refresh)
SMF Shop


I have done some great efforts but the forum is really slow to loads: 2 min ...

My.conf that i modified a little ...
I'm french if it helps talking in french, just tell me :)
Thanks.

I have already read your topic, but i saw some problems seems with Innodb on this topic.
So i'm not really sure.

Actually performance problem is solved, but it can be better i think.
