[mapserver-users] Using Fast CGI with MapServer to alleviate poor

The idea that CGI is naturally a much slower situation than a
long-running process is a bit of a red herring in the case of
Mapserver, and I say that as someone who is anal retentive about these
things. Unless your Mapserver installation has some naturally latent
components (database connections, primarily) you'll find that moving
from CGI to FastCGI is worth about 15ms per request.

Yes and no. If you are experiencing noticeably poor performance (you
can actually *see* it being slow) the only place that the CGI overhead
could be the cause is if you're connecting to Oracle or SDE for some
of your layers. If that's not the case, look elsewhere first, the very
small gains you will receive from moving to FastCGI will not change
your underlying problem.
