I've tried the "simpler patch" on my system and it makes no difference for me.

Does it make no difference to Jens' patch, or no difference to an
unpatched kernel?
No difference to an unpatched kernel. I didn't think of stacking the patches.
BTW, switching from cfq to noop or deadline also improved things a
bit for me.
Will try that.
