Memory usage

[Sigmar Muuga <me...@gmail.com>]

Hello,
my app is about 3-4 pages and its running with spring.
It has database connection and it uses basic authentication.

What should be the maximum memory usage for this? At the moment it takes
422megabytes and this is definately too much for application without any
load and traffic.

Are there any checklist for running wicket appliction with minimal memory?

If there is no load and traffic, it isn't Wicket occupying your memory.

Try using something like YourKit (http://www.yourkit.com/) and see
what takes up all that memory. Another quick test you can do is see
how much it is when you start up. If it is much lower but grows over
time, you can try triggering a GC run (e.g. through JMX) and see if it
drops down to roughly the startup level. If it is, nothing to worry
about. If it doesn't, you either have a leak, or you're doing some
crazy caching or something.

Seems that it loads all the stuff into the memory from jars..

So your jit loader is very optimal ;)
