I believe that with Mule (at least) some operation that VM does in the
background is O(N^2) in buffer size; on a 1.8GHz AMD64 system I only
see the freezes when INBOX gets above about 60MB, but then things
rapidly get worse.

File I/O, specifically autosaves, can take a long time too if you have
many (> 10) VM folders open.

Sorry, not at the moment, but I plan to work on this a bit in the near
future.  You should try reporting on the VM channels (M-x
report-vm-bug is the way to go, I think).
