Comment 321 for bug 131094

My understanding of the writeback option is that it greatly decreases the file system's tolerance for crashes, and could result in the file system being put in an inconsistent state, with resulting data loss. This seems a high price to pay, so this is clearly not a good solution.

I would also like to point out that performance degrades even if I am only doing heavy reads, but not writes. In that case, the writeback option shouldn't improve performance at all.
