[Mapserver-users] Performance Drain

I'm just starting out with Mapserver (about 10 days ago). My app uses OGR
to connect to MapInfo .tab files. The map file is below.
I am using:
Dell Server with Dual Celeron 600MHz's
1GB RAM
Windows 2K server
MapServer 3.6.6
PHP 4.3.3
MapLab 2.0.1
OGR --> MapInfo .tab's
My problem is that when the application is run, the CPUs run at 55% for a
second or two. If I increase the image size to 750 by 584 it peaks out at
100%. This occurs when only one person accesses the application. It will
not be open to the public, but the performance is less then optimal.
Does anyone have any suggestions on where I should look to improve
performance?
