As we have OLS paper on the table we were thinking here at Bull what bench t run and on which kernel. If we want trying to compare ext3 and ext4, I guess we should at least show that : - ext4 has equivalent perfs than ext3, - improvements done for ext3 are still in ext4 (mb alloc, del alloc...). So we were wondering what's best to do : - run on 2.6.19 (includes del alloc and mb alloc if I am not wrong), - run on 2.6.20 (lacks mb alloc), - select relevant benchs (iozone...). What do you think ? Thanks. jean-pierre
