This is a surprise to me, the performance tests we have handy show a steady performance increase over the years (but I don't have data points for the 2.6.x series), see slide 81 in this presentation: http://www.slideshare.net/geosolutions/enterprise-gsgwcdeploymentbenchmarks-foss4g2015v0103 You sure nothing else changed between 2.0.2 and 2.6.2, like, the number of layers, the amount of requests you normally handle, the type of requests? > > 2.
