Hi, I am running Windows 2k3 server, 3gb ram, 2.66ghz Xeon processor, eAcellerator, ISAPI Rewrite 3.x, and Drupal 5.7. I was having issues with CPU and php-cgi.exe process usage where people would visit the site and it would take long periods of time (10 seconds and more) to load. CPU usage would peak and stay around 80 percent.

I then turn on Drupal "normal" caching, which dropped everything down to below 10% usage, however, for people who log into the site, the pages load slowly again and CPU usage goes up.

I have been asked to design an Intranet for our department.What software can i use? I'm not that clued on web design software.

Your help will be gladly appreciated.
