Performance tuning Wicket[1.5]...
Hi
Im seeing a load on our server.
Tried these settings in wicketapplication:
getPageSettings().setVersionPagesByDefault(false);
getStoreSettings().setInmemoryCacheSize(200);
And in our MainPage:
setVersioned(false);
All of our services are being cached, so it's not the backend thats the
problem.. Im using LDM's everywhere.
Our main page are using ajax to refresh itself. And load
turns linearly bad, until max load on somewhere around 100 sessions.
Memory are not a problem, wicket app uses very little around 100 mb and
server has 4gb. CPU are a AMD opteron 2.2 ghz.

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.

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.

Maybe bottleneck is somewhere else? SQL request maybe? Some eager loading...

A little feedback. First I tried visualVM (did not provide enough detail
for this "extreme" optimization), then jprofiler (had trouble getting it to
work), but yourkit gave the best result. However there was little I could
do, other than removing an unnecessary filter (character encoding fix for
tomcat/wicket).. Other than that there werent many hotspots.
