The mystery has been solved.

You can call off your bsearch - I found the culprit.

For the 2.6.10-rc2 tests I was running with the patch from Andreas that added large ext3 inode support (in order to also test the ext3-256 case). For the -mm2 test I wasn't.

This patch was supposed to have no effect if large inodes were not setup at mkfs time. Unfortunately it does have an affect as it also removes the in-place xattr modification logic from ext3_xattr_set_handle(), so every xattr set becomes the same as a delete+create pair. In plain -rc2 and in -mm2 an xattr set of the same size will be done in-place. As every xattr set is of the same size in dbench3 this made a huge difference.
