Hi, Do you mean that wsgi was 500 times faster than FastCGI as the numbers suggest? Anyway, we should get interesting and comparable test results about WMS speed next week from the FOSS4G conference (http://2010.foss4g.org/wms_benchmarking.php). Last years results can be read at http://www.slideshare.net/gatewaygeomatics.com/wms-performance-shootout
