Randall Hopper: | From profiling dxexec, I've found that 20-25% of it's time in the |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. -- Randall Hopper [EMAIL PROTECTED]
