As Paul said Jack DSP load  is the percentage of the JACK
period  
actually used to run the process cycle. On MP machines this
remains  
true, and what you will gain with jackdmp over jackd is that
this  
value can be lower, if parallel processing of clients is
possible in  
your jack clients connection topology.
