Looking for a Linux Administrator to configure Apache with some load balancing software. I have 4 servers, 1 dedicated for MySQL, 2 for apache, and 1 to act as the load balancer. As it stands, I am using mod_proxy_balancer and it seems to be running great, but its taking apache/php a lot of time to generate the pages (up to 7 seconds when under load, where on my current vps, it takes less than 1 second). It looks like just an apache/php configuration that needs to be adjusted. Payment will be via GAF escrow. I need this done ASAP.
The servers are running CentOS 5 and I have installed webmin on them for ease of use. SSH details can be provided if preferred over webmin.
