While it indicates that deltas are taking a long time to apply (or are somehow not optimally organized for IO), I think it indicates either: 1. Your history is very deep and there are an unusually high number of deltas for each blob. What are the total number of commits? 2. You have have huge (binary) files checked into your repository. Do you? If so, why isn't the code in streaming.c kicking in? -- To unsubscribe from this list: 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
