Hi, I added some time logging code to git-merge-recursive to see exactly what we spend all the time on in merges which involves many changes, such as a merge of a slightly modified v2.6.12 and an unmodified v2.6.15. I turned out that the rename detection took almost 10 minutes on my machine. More specifically, git-diff-tree -r -M --diff-filter=R v2.6.12 v2.6.14 takes ~9 minutes with the current 'next'. With 65416758cd83772f2f3c69f1bd1f501608e64745, which uses the delta code to compute the similarity measure, the above git-diff-tree invocation takes 1.50 minutes. - Fredrik - : send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
