Solving the ext3 latency problem

Great article! It's nice to see that all this discussion is coming to a sane conclusion.

It's a little disturbing to see data=writeback becoming the default. Is the performance gain really so great that it's worth being less secure by default?

Yes, great article. The lkml discussion was also fascinating.

We have _severe_ latency issues with ext3 and our RAID arrays, sometimes causing our servers to appear to freeze for tens of seconds during disk writes. A safer 'writeback' mode that eliminates these latencies will be a huge win for us.
