Comment 370 for bug 131094

I was trying this patch in Arch Linux and reading some clarifications
in the forum (https://bbs.archlinux.org/viewtopic.php?id=108516).
Apparently, this patch is not about IO performance, but only the
scheduling of process in different tty. So, if you launch all in the
same tty is not going to help at all.

> When compared with 2.6.15 in feisty, heavy disk I/O causes increased iowait times and affects desktop responsiveness in 2.6.22

> this appears to be a regression from 2.6.15 where iowait is much lower and desktop responsiveness is unaffected with the same I/O load

> Easy to reproduce with tracker - index the same set of files with 2.6.15 kernel and 2.6.22 kernel and the difference in desktop responsiveness is massive

> I have not confirmed if a non-tracker process which does heavy disk i/o (especially writing) replicates this yet - will do further investigation soon
