Are you sure you aren't comparing filesystems with different mount options? Async comes to mind first.
a) ext3 and xfs are logging filesystems, so the problem with asynchronous metadata updates possibly corrupting the filesystem on a crash doesn't arise.
No, they have a different, though unrelated issues. I didn't notice which filesystem and which options were used for the benchmarks, that's why I was asking about it.
b) asynchronous metadata updates wouldn't have any performance benefit on a dd if=/dev/zero of=tstfile.
I was not aware that the tests were this simple.

I usually do, however in this case it was intentional.
