Hi all,
Will the mapserver CGI program multi-thread on an MS4W installation. I
noticed many "mapserver.exe" image names in the task manager on my
server. Assuming each image name corresponds with each request or
thread, will the OS delegate the processes to other CPU cores if
available? I currently only have a single core Xeon, but am wondering
if a multi-core CPU could be beneficial with Apache and Mapserver (MS4W).

Someone else already responded, but I just wanted to say this really simply
and clearly for everyone.
MapServer is a cgi, so Apache (or IIS) is creating a mapserver process for
each request that comes in. This is good for multi-processor/multi-core
machines because when several mapserver requests are running at once, they
will normally be distributed across the available cores by the operating
system.
So, by architectural design MapServer cgi takes advantage of multi-core
systems well for non-trivial load situations.
What MapServer doesn't do is try to distribute a single request over multiple
cores. To do so requires a great deal more complication in the core of
mapserver, and isn't - to my mind - justified.
Best regards,
