I used git.git rather than linux.git because I didn't want to wait several days for the results (plus this is my primary machine which I'm actively using). Results were similar to what you saw: 5302.3: index-pack 0 threads 14.85(14.10+0.66) 5302.4: index-pack 1 threads 14.65(13.83+0.63) 5302.5: index-pack 2 threads 9.11(14.40+0.80) 5302.6: index-pack 4 threads 6.89(17.03+1.32) 5302.7: index-pack default number of threads 7.72(16.15+1.15) Thanks for providing exact instructions for running the test; I had never done it before, thus didn't know how.
