------- Additional comments from [EMAIL PROTECTED] Fri Jun 15 12:43:19 +0000 2007 ------- Reading the cachegrind data, it seems that of the 440k lock takes on writer startup, some 190k of them (~40%) come from the store code: which it seems uses some highly granular locking approach [ where a single-lock would be rather better for our use-case ]. The attached patch fixes some part of this; but there are clearly many more efficiency wins to be squeezed from the store code, more CRC verifiction to remove eg. The patch saves ~100k lock take/un-take pairs, and ~19m callgrind pseudo-cycles (~1%) though we know locks cost substantially more than their pseudo-cycle weight. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
