Re: ext2/3 performance regression in 2.6 vs 2.4 for small interleaved writes

[Dave Olien]

2.4 does not have deadline scheduler.  But the 2.6 deadline scheduler
is more similar to 2.4's scheduler than is the anticipatory scheduler.

Re-try 2.6 with deadline scheduler will remove some of the additional
scheduler policies that are present in the anticipatory scheduler.
