I’m not sure if that is still the case with modern SSDs, but I think the idea is that by putting everything inside of zip files you reduce the number of stat calls that Python needs to do (they flip side of this is that pkg_resources is incredibly slow because it needs to issue a ton of stat calls on import). ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA
