No effect at either 50 or 100. The more that I think about it the more it seems possible that the pathname hashing is what may be causing the problem. Not only did bisect point to 1d6b38cc76c348e2477506ca9759fc241e3d0d46 but the directory which contains the bulk of the space has many files with the same name located in different directories: results/MT/Math/10000/0-11-AdjLite.deg results/MT/Math/10000/0-12-AdjLite.deg ... results/MT/Math/30000/2-11-AdjLite.deg results/MT/Math/30000/2-12-AdjLite.deg ... results/Rand48/Math/10000/2-11-AdjLite.deg results/Rand48/Math/10000/2-12-AdjLite.deg ... results/Rand48/Math/30000/2-11-AdjLite.deg results/Rand48/Math/30000/2-12-AdjLite.deg ... For example the name '0-11-AdjLite.deg' occurs in 63 directories and none of those occurrances are likely to delta against one another very well. Also most of these files only have 1 or 2 revisions, so there is very little per-file history. -- Shawn. - 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 Fri Apr 21 03:56:45 2006
