From d9545c7f465ed103df44cd93caddfdd265757779 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Mon, 25 Apr 2016 21:17:28 +0000 Subject: fast-import: implement unpack limit With many incremental imports, small packs become highly inefficient due to the need to readdir scan and load many indices to locate even a single object. Frequent repacking and consolidation may be prohibitively expensive in terms of disk I/O, especially in large repositories where the initial packs were aggressively optimized and marked with .keep files. In those cases, users may be better served with loose objects and relying on "git gc --auto". This changes the default behavior of fast-import for small imports found in test cases, so adjustments to t9300 were necessary.
