Hello,
I have a dedicated server with this configurations:
AMD Opteron 4174
6x 2.30+ GHz
16 Go DDR3
Internet speed : 200 Mbps Centos 5 with Plesk 9.5
The problem is that with a 20 or higher number of members on line, the cpu charge is 100%.
The problem is that dolphin and ray chat kill the cpu.
The most loaded file in the server is:
flash/XML.php & /member_menu_queries.php
With all my respect.
