Re: Performance improvement on IBM HTTPServer

If you have Apache (does not have to be on the target server), you 
probably have the excellent "ab" command installed.

Something like:
ab -n1000 -c5 -k1http://hostname/app.cgi
ab -n1000 -c5 -k1http://hostname/app.fcgi

...would give you nice results, like:

  99%    126
 100%    195 (longest request)


Your "Request per second" should show a performance gain when running in "FCGI mode".
