File System , I/O performance.

[Cesar Inacio Martins]

Studying about JFS , found this nice database microbenchmark from OpenLDAP
project...
There is no big player here... only lightweight databases.

What caught my attention is the JFS performance at FS test , "without" the
journaling overhead.

The comparison is with : btrfs, ext2, ext3, ext4, jfs, ntfs, reiserfs, xfs,
and zfs (Linux)

Just as nice information .

Cesar:

That matches my own testing indicating that EXT2 should be the filesystem
of choice for database chunks. In this test it dramatically outperformed
all other filesystem types on Linux except JFS and only when the JFS
journal was written to a virtual drive in memory.
