I get much closer numbers if the patches directory is already in cache...data=ordered means more contention for the disk when trying to read the patches. If the patches are hot in the cache data=writeback and data=ordered both take about 30s. You still see some writes in data=writeback, but these are mostly async log commits. The same holds true for vanilla git as well, although it needs 1m7s to apply from a hot cache (sorry, couldn't resist the plug ;) -chris - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Wed Apr 27 05:52:36 2005
