I followed the instructions and edited httpd.cong accordingly. This
seemed to
go right, because now my server is answering also for requests which I

JMeter test
with 10 and 20 concurrent users give similar output with both cgi and
fcgi requests, 
about 5 images per second. Throughput is about 600 KB/sec. After reading

I was awaiting about two times more speed for fcgi.

Is there something more I should do, in addition to making fcgi module
to load 
and commenting out the few lines from httpd.conf file?

I had only one raster layer in my test, and I added the line
to layer definitions. I am not sure if it is needed for raster layers
which are read through tileindex. My tileindex shapefile has about 13000

polygons so I guess it should gain from using fcgi. Images themselves
processed in typical Mapserver way, they are uncompressed, tiled, and
