Hi Jeff,

In the meantime, we started setting up a testing environment to evaluate
the performance of combinations of MS4W/PostgreSQL/PostGIS.  With a
fixed DB (PG 8.4/PostGIS 1.5 binaries for windows) and a table of a few
vector features, we used the following ab command on urls pointing to
MS4W 2.3.1 (CGI an FCGI) and MS4W 3.0 b7.  Results are intriguing.

The command :

ms4w_3.0_beta7\Apache\bin\ab -n 100 -c 10
"http://localhost:8030/cgi-bin/mapserv.exe?map=../../../maps/maps/test.map&mode=map"

(ms4w 2.3.1 was set up on port 8031)

Conclusions : the throughput for FGCI is 4 times of CGI; 3.0 is *slower*
than 2.3.1 in CGI mode

We installed both packages the same.
