Ok I have tried to search the archives but perhaps I am not a good
searcher =)

I wonder why there is so big difference between max resident size and
accounted memory. I use a cache_mem of 4 mb and tried both LFUDA and GDSF
technics and got similar results.
By the way what is accounted memory exactly? I just started this cache 3
minutes before I took the cachemgr output.

Briefly I am little bit confused.
