[Bug 131094] Re: Heavy Disk I/O harms desktop responsiveness

[Jeff Epstein]

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.
