No what I meant was that the system er performing as good as it can, without clustering etc. There weren't much stuff to optimize on. 2012/8/31 Alex Shubert alex.shub...@gmail.com Maybe bottleneck is somewhere else?

Nope this was just the app taking much resources.. It scales linearly with number of sessions. Im using ajax on the main page, otherwise I would have tried to make it stateless. 2012/8/31 Thomas Götz t...@decoded.de Hm, Java leap second bug? http://blog.wpkg.org/2012/07/01/java-leap-second-bug-30-june-1-july-2012-fix/ -Tom On 31.08.2012, at 12:19, nino martinez wael nino.martinez.w...@gmail.com wrote: No what I meant was that the system er performing as good as it can, without clustering etc. There weren't much stuff to optimize on. 2012/8/31 Alex Shubert alex.shub...@gmail.com Maybe bottleneck is somewhere else?
