It is not:

Single pack = 17.1s 66 packs with commit f7c22cc6 = 18.4s 66 packs without commit f7c22cc6 = 24.9s

The point is that having many packs doesn't impose a significant overhead anymore when comparing to the single pack case.

Having only to set gc.auto=0 to disable it entirely is also a good thing.

Please tell me why if this is still the case.
