My apologies for the late reply, I haven't had the time yet to run some additional tests.
Tuning the default parameters does make a huge difference: a quick test with the following values: servicemix.corePoolSize = 60 servicemix.maximumPoolSize = 100 servicemix.queueSize = 256 instead of the default servicemix.corePoolSize = 4 servicemix.maximumPoolSize = 32 servicemix.queueSize = 256 showed that servicemix obtained a troughput of about 1850 req/s, so that's an impressive increase in troughput. My modified values are most likely overkill, but the default values on the other hand are imho a bit on the low side: when i tried tests with those values with more than 32 concurrent users, ServiceMix would often lock up, and refuse to process any requests.
