Well.. ab2 is an apache benchmarking tool. But I'm under the impression that it's intended to measure the performance of static pages.
It doesn't use cookies, does it? If I recall correctly there should be a possibility to specify a cookie value there, so you might be able to reduce the number of created sessions somehow. -Matej Sebastjan Trepca wrote: > I used the default resin3pro configuration.
