We have the following box which has everything (Apache, MySQL, PHP).
Windows 2003
Xeon Processor E5504 @ 2.00 GHz
8 GB RAM
PHP - 5.2.13
MYSQL - 5.1.49
Apache - 2.2
Moodle - 1.9.9
Currently this system is stable to support 250 - 300 concurrent users without any performance issues.
We have a similar hardware config available and we would like to implement load balancer so that the setup supports more concurrent users.
I am not a techie. Can someone help me out to set it up ?
