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

[Rocko]

Yes, the stock 2.6.36 kernel (which is in the weekly builds linked to in
comment #358), has a patch to improve responsiveness (this is from
http://kernelnewbies.org/Linux_2_6_36):

1.7. Improve VM-related desktop responsiveness

There are some cases where a desktop system could be really unresponsive
while doing things such as writing to a very slow USB storage device and
some memory pressure. This release includes a small patch that improves
the VM heuristics to solve this problem.


ie it helps improve responsiveness for a particular case. 

FWIW, I haven't noticed any major desktop slowdowns on my system with
2.6.36 over the last 6 days.
