I carried out some tests on ext3/ext4 before/after patch. Most tests are repeated for 3 times so as to get an idea about the variations. The ":jsize=8" notion means "-J size=8" in action. The overall deltas are -0.3% for ext4 and -3.3% for ext3. I noticed that the regressions mostly happen for the "-J size=8" cases. For normal mkfs, ext4 actually sees +2.5% increase and ext3 sees only -0.8% drop. I don't find any misbehaves in the graphs. So in general I think the test results are acceptable.
