[OSGeo-Discuss] WMS Performance Shootout presentation/results

[antti roppola]

It was really interesting. The very close results suggests to me that the
bottlenecks were external to the WMS and more related to external
limitations like the ability to supply things like I/O. It would be
interesting to have profiling data on where the response time was spent. For
Mapserver it'd be a simple case of running Valgrinf and KCacheGrind:

http://kcachegrind.sourceforge.net/cgi-bin/show.cgi/KcacheGrindIndex

Case point. We had an in house app for crunching big raster and KCacheGrind
showed us that an external library was the biggest bottleneck.
