[opendx-dev] Re: dxexec: 20% perf speedup

 |single-process case is spent locking and unlocking mutex locks (on SGI).
 |AFAICT these locks add unnecessary, avoidable overhead to the
 |single-process case.
 |
 |     I can cook a patch so that mutex locks are only used in dxexec when
 |"nprocs > 1".  But before I do, I'd like to find out whether the DX
 |committers would be willing to commit this patch.

Perhaps worth mentioning that I already have a patch and the 20-25% savings
is real savings, not estimated from prof numbers.  However the patch needs
refined to be ready for a commit.
