Comment (by tibbs):
I just wanted to note that this has implications beyond AFS. Basically,
rsync can in some situations run chewing 100% CPU and transferring no
data. This only happens on the "drpms" directories and as far as I can is
due to the large number of files there and the fact that they are small,
so that the rsync thread which transfers data ends up stalling waiting for
the main thread to tell it what to transfer. In some cases the connection
will stall long enough for the sending side to time out.
For me this significantly increases the amount of time it takes to sync
content between my machines. So splitting the "drpms" directories would
definitely help. Still doesn't help come up with anyone to actually fix
the code, of course.
