able to serve multiple request I parallel is not a MapServer issue but an OS issue.
So if you OS can detect multiple cores it will execute processes I parallel on
the different cores. Therefore MapServer doesn’t need to multi-thread for
you to serve multiple request I parallel.<o:p></o:p></span></font></p>

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).<o:p></o:p></span></font></p>
