I concur this, I watched a DVD tonight, and actually it got so bad
I had to reboot at one point as the it became too jerky to watch.
free output looked like this at this point...
total used free shared buffers cached
Mem: 254960 253252 1708 0 24116 174500
-/+ buffers/cache: 54636 200324
Swap: 248996 20848 228148
It appeared, that rather than free the cached buffers and reuse the
memory, it preferred to hit swap space. Streaming I/O performance seems
to have taken a hit lately.
(This was 2.4.1-ac9 btw)

Dave.
