10.0pt;font-family:Arial;color:navy'>I’m experiencing similar problems
with cpu usage and general speed of performing simple tasks such as panning
around a map. The test server I’m using is Pentium 4 HT 3ghz with 1gig of
RAM running Windows Server 2003 and serving MapGuide (in the Windows IIS
configuration) being the only service running on it. I currently have about
300mb of data in SDF format (imported from SHP) and the problem is seen even
when zoomed in on the map. <o:p></o:p></span></font></p>

several tiles not being displayed when using the <st1:City w:st="on"><st1:place

on the map tends to spike the cpu usage to the ceiling on my test server. I'm
not sure if it would support the number of users we would require in a
production environment. I've tested using both the .fcgi and MapAgent.exe
as the web service extension configuration. As some of the other threads
mention, I did see an increase of reliability with the mgserver.exe service not
dropping when deployed with MapAgent.exe defined as the web service extension
