Parallel creation of ESPs was disabled in October '13 to fix a problem with some regression tests failing. It would be good to figure out the specific problem(s), if any, with parallel creation and fix those, so that we don't have to take the performance hit of serial creation. It costs about 15 seconds to fixup a 64 d-o-p plan when ESPs must be started serially, versus ~0.5 seconds if they are started serially. |
