I'm in the same boat as you... I just upgraded to current SVN of
nuvexport.  I haven't ran it in about a year, but I want to offload
some shows.  It's taking me about 3.5 hours at ~6.5 fps to complete a
30 minute show.  It used to be much faster.  I'm not quite sure what
the problem is, but it is very annoying.  Searching the mailing lists,
I can see that speed has always been an issue with nuvexport, but I
never really had any major issues until recently... I'm not quite sure
what the problem is.

Here is my readout from top:
 PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
