Andy, To be more specific:
I am using GeoMoose. GeoMoose draws each layer separately so we do benefit by having a multi-core processor even if there is only one user. We also are using a WMS Service so air photos is for the most part a non issue. If my understanding is correct hyper-threading has up to a 20 percent increase in speed. However, the performance increase is highly application specific and in some cases performance may actually be lower with Hyper-Threading enabled.

I'm not sure if mapserver itself will use mult-threads, but if you have multiple requests comming into a website, apache/cgi/mapserver/etc will use multi process/threads/etc. Its tough to say the performance increase. I'm host several maps on a dual-core box, and the cpu's sit around 2 percent. And with lots of arial imagery you might hit disk io limit before you hit cpu limit. (However, I have had some mrsid files that were really cpu intensive to uncompress, they were cpu bound). Are your cpu's even pegged? So, I guess, the answer is, it really depends on a lot of different variables. -Andy _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
