My sites have roughly 3500 posts and we are using wp-cache.
i get over 200000 unique visitor a day and running on Opteron Dual core (175) with 4GB of RAM and 74GB of 10k RPM HDD
But my server load is over 6.xx all the time and i only use basic plugins such as akismet, wp-cache, and youtube.
The server is hosting my blog alone. Any pointer on Apache tweaks or MySQL tweak?
running apache 1.3 with MySQL 4.1 and PHP 4.4.4
