Not to make a habit of resurrecting old threads ( haven't had much time 
in the past couple weeks ), but did you have any luck here?
I'm on the road at the moment, so can't look at the specifics of my 
setup, but I have one netbooted frontend (an gigabit mb/intel i5) that 
became *very* sluggish in the recorded programs screen after a system 
update.  Reverted back to the earlier version of the kernel I was 
running on that machine, and it became much more responsive, IIRC, it 
was somewhere around the 3.10->3.11 area. At the time I tried doing a 
disect on what specific commit had skewed my system, but there were 
hundreds of commits at the time, and I ran out of time.

Know its not much help, but might give you and idea on where to start 
looking.
