Are you responding to my message? If so, I can tell you that I'm 100%
certain my slow UI problem is unrelated to disk performance. It has
nothing to do with what is or isn't going on with the disks. In
particular, it's usually when there's no significant disk activity
because nothing's being recorded or commflagged or anything. IO
starvation problems would greatly affect playback performance, which is
not what I'm seeing. I can watch HD shows while one or two commflag
processes are working in the background.

What varies is whether I have just ended playback or not. Before
playback, menu navigation is pretty snappy, but afterward, there's a
constant delay of more than a second moving from one program to the next.
