| |
I've noticed that XFS's filesystem has a separate pagebuf_daemon to handle caching/buffering.
Why not make a kernel page/caching daemon for other filesystems to use (kpagebufd) so that each filesystem can use a kernel daemon interface to handle buffering and caching.
I found that XFS's buffering/caching significantly reduced I/O load on the system (with riel's rmap11b + rml's preempt patches and Andre's IDE patch).
But I've not been able to acheive the same speed results with ReiserFS :-(
Just as we have a filesystem (VFS) layer, why not have a buffering/caching layer for the filesystems to use inconjunction with the VM?
Comments, suggestions, flames welcome ;)
Shawn.
