Hi,
I would also add to others comments that you should probably check to 
optimize your mapfile as much ass possible. That's quite often a bottle 
neck. Check:
http://mapserver.gis.umn.edu/docs/howto/mapfiletuning

And also check to have shapefiles (fastest) or PostGIS DB (fastest for 
complex queries or complex classification) datasource.
