one of the issues that may be affecting you is the size of the  
'metatile' that is being created.  MapServer ends up drawing a much  
larger map that it normally would be asked to.  This has some  
definite implications for your configuration.  You can try reducing  
the tile size and/or reducing the number of tiles in a metatile to  
get the combined size down to something that mapserver can produce in  
a reasonable time.  For instance, try tile sizes of 200 x 200 and  
either 4x4 metaWidth/metaHeight and see if you get a bit more out of  
your dev server.  Note that is a pretty good machine for this type of  
stuff so I am a bit suprised.  Have you tried benchmarking  
performance with just mapserv cgi on that mapfile?  We've tried to  
keep the tile.php pretty lean but there could still be room for
