Hi James,

    I already did many tests a couple of months ago to see if fastCGI 
was worth the efforts, and as soon as it worked, I noticed a good 
difference of performances.  The map loaded much faster.  At the bottom 
left of my internet browser, files transfered from the server were 
downloaded much faster in fastCGI mode than normal.

    But I also did real actual tests using a small application called 
http_load, you can get it at : http://www.acme.com/software/http_load/

    Well, maybe Jeff McKenna knows a better way to do it...

    I definitively noticed a difference in performance between normal 
CGI and fastCGI.  Try to make a file containing url of a GetMap request 
and test it with http_load with normal CGI and fastCGI configurations to 
see the difference.

    To disable fastCGI, add quotes to your httpd.conf where the module 
is loaded :

    #LoadModule fcgid_module modules/mod_fcgid.so

    This should be enough to disable it without problems.  Then restart 

    You can also see which modules are currently loaded with :

    go to --> /ms4w/Apache/bin
    type the following --> httpd -t -D DUMP_MODULES

    and see if your fastCGI module is there or not.

    A tip : when you start/restart/stop apache, be sure do it in a 
command window and not by clicking on the .bat file in windows mode.  
That way, you will be able to see if there is any error message.

    Best regards,
