To segregate the historical commits (can't remember why), I originally placed their pack in an alternate object store, but later I found that a *.keep file does the job as well. This gives a considerable speedup in git gc. It takes some more disk space but OTOH you might then run gc more often and have fewer loose objects. real user sys (tested in this order) 1m15.900s 0m59.732s 0m4.336s gc after clone&graft without *.keep 0m23.162s 0m17.549s 0m1.588s gc after clone&graft with *.keep 0m06.932s 0m04.440s 0m0.588s gc after clone&graft&gc with *.keep 0m32.214s 0m24.138s 0m2.284s gc after clone&graft&gc without *.keep Total size of .git/objects/pack/ was 90592 KiB without *.keep and 97397 KiB with *.keep. So *.keep reduced gc time by 70-80% but increased disk space usage by 7.5%.
