Actually, that was the timing when I first pushed the change. With the improvements submitted throughout the year, we can do counting in 50ms, on my same machine. > But I think we are comparing > apples to steaks here, Vincent is (rightfully) concerned about process > startup performance, whereas our timings were assuming the process was > already running. > I did some timing on loading the reverse index for the kernel and it is pretty slow (~1200ms). I just submitted a fix to do a bucket sort and reduced that to ~450ms, which is still slow but much better: https://eclipse.googlesource.com/jgit/jgit/+/6cc532a43cf28403cb623d3df8600a2542a40a43%5E%21/ -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
