cachemaster

Cachemaster is similar to VMTOUCH, but with more functions. Such as kick page cache, warmup/readahead data, lock data in mem, stat page cache, stat page cache in realtime mode, by file or directory~ Personally, I think the most usefule function is real-time-statistic of page cache. You can see the page cache thrashing when kernel do page reclaiming.
