Webmaster by trade learning the usual "testing" way my way round servers. Im playing with a big 24Core LAMP server with 32Gb Ram and 100mbps connection.
Ive tweaked and tweaked at apache config but still having issues over user levels.
After doing some load tests it seems only to be handling 350 concurrent users (at a page load time of 10 seconds) after this the 10 seconds sky rockets.
Which is puzzling when Mysql/CPU/RAM are ticking over. (which is why i was looking at max clients in apache).
Any ideas what else what could reduce the page load time to below 10 seconds with say 1000 users?
I/O requests is fine too.
EDIT - this is a PHP website, dynamic content fed from MySQL. Index page is about 1.5MB to download in total.
Should also add between 50 and 250 current users website load time was under 3.5 seconds.
