-----------------------------------------------------------------

tested on an demoserver (linux, quad-core, 8GB RAM):

A page executes 20x render(...) and consists of 8-10 ssp renderlets

200 concurrent users (10 sec click delay) average respone time 160ms (see attachement)

> during profiling session we detected that rendering ssp is very slow. A lot of time is used to execute scala.tool.nsc.interpreter.AbstractFileClassLoader.findClass. Seems that each execution the classes are (re)loaded. IMO this should not be the case.
