From: Kevin Burton on 21 Apr 2010 22:40 I'm trying to find out a way to tune the Linux VFS page cache. A number of caching systems like memcached, MySQL/InnoDB page cache export stats which can help you determine how efficient you are with memory. The key values I need are number of hits from the page cache and total requests to the page cache. These should just continually increment and rollover until we run out of unsigned long space (2^64). Is it possible to do this with Linux? I'm pretty sure it's not..... I would LOVE to be proven wrong. I'll buy anyone a beer who solves this problem for me :) -- Join the Spinn3r mailing lists: http://groups.google.com/group/spinn3r-announce http://groups.google.com/group/spinn3r Founder/CEO Spinn3r.com Location: San Francisco, CA AIM/YIM: sfburtonator Skype: burtonator Work: http://spinn3r.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
