ext4 doesn't implement delayed allocation (yet).
I made some observations regarding comparative benchmarking of filesystems
when releasing 2.6.19-rc1-mm1. They seem to have been ignored ;) See

Yeah, and because of this: "Although this doesn't seem to make much
difference with ext3" which is what I observed, too, in some other
benchmarks.
