I made a very quick test with what I had handy, a GeoServer 2.4.x, Oracle JDK 7 (which has known scalability issues) and not even the Image/IO native PNG encoder enabled (so, I'm using the slowest PNG encoder in the lot) with a core i7 820 (three years old CPU) I get a throughput that is 2.4 times faster than yours (without even trying... but I'm under Linux 64 bits, that might be a factor): [image: Inline image 2] CPU consumption was around 60%. Btw, This JMeter setup is a bit different that what I'm used to, the various zoom levels are not run sequentially, in isolation, but all together at the same time, using 10 threads, so the real throughput is the TOTAL one, 3.4r/s, the throughput value associated to the various zoom levels is apparently meaningless? The size of the output image is also a factor, it's "big" compared to the sizes that were used for the FOSS4G benchmarks, at 1272x1261 it is roughly 4 times bigger than the average one used in last public benchmarking effort. When I have time I'll run some tests with OpenJDK and PNGJ and report back, and also have a look at profiles, to see if there is anything obvious to optimize.
