Today I start playing with Linus's vm in 2.2.0-pre1 and I changed the
semantics of many things and I added heuristic to avoid that one process
trashing memory will hang other "normal" processes. This my new VM I
developed today is _far_ better than sct's ac11 vm and anything I tried
before. I would like if somebody could try it also on low memory machines
and feedback what happens there. I don't have enough spare time to test
it on many kind of hardware too.
The same benchmark that was taking 106 sec on clean 2.2.0-pre1 to
dirtifying 160Mbyte of virtual memory (run with 128RAM and 72swap of phis
mem), now runs in 90 sec but this is not the most important thing, the
good point is that the cache/buffer/swap levels now are perfectly stable
and all other processes runs fine and get not out of cache even if there's
a memory trahser running at the same time.
Comments?
Ah, the shrink_mmap limit was wrong since we account only not referenced
pages.
Patch against 2.2.0-pre1:
