Wow! Nearly missed this one:
"Most Linux block device drivers use a generic tunable "elevator" algorithm for scheduling block I/O. The /sbin/elvtune program can be used to trade off between throughput and latency. Given similar loads, the ext3 file system may require smaller latency numbers as provided to the /sbin/elvtune program in order to provide similar results to the ext2 file system."

Has anyone played with this at all? I saw a reference on the kernel docs for 2.6 to the tune of elevators being redundant with this level of the software. Any ideas?
