I have a P4 2.4 with 1GB RAM dedicated server 100Mbps net connection
It runs WHM 8.8.0 cPanel 8.8.0-R73 RedHat 9 - WHM X v2.1.2 apache (1.3.29 (Unix)) mysql (4.0.15-standard)
This machine is entirely use for just 1 domain with a vBulletin board. The site has about somewhere from 200+ to 800+ users online concurrent depends on time of the day.
When the number of users about 300- (less than 300) the server seem to react normally (Not Slow)
However, when the number of users increase at night (7mp - 5am PST) the server react extreamly slow (I mean really really slow) and it sometimes refuse to dislay page and not to load images as well.
1. Is this because of MySQL not tuned or Apache not Turned? How do I go about finding what need to fix?
2. I have include the 2 results (when site not busy & busy) of the script Jeremy provide, with the numbers shown, How I optimize MySQL to be the most efficient for my site?
3. With the hardware I have how many users I could have on the site just to browse the vBulletin board?
Thank you in advance for helping.
