> After introducing MemoryPolicy concept and related settings to Ignite there were several cases when users run into problems with default configuration.
> It seems that approach with allocating 80% of available physical memory causes confusion among users sitting on 32bit systems including versions of JMV (example [1]) and also hurts stability of TeamCity.
> We need to rethink these settings and make them easier to use.
> Also it turned out that memory allocation process differs in cases of PDS on and off; it must be properly documented.
