Revision 9dd5245c1043dd18fd7b3f44b9e51eef7e4b58d8 authored by Jeff King on 02 February 2012, 08:24:28 UTC, committed by Junio C Hamano on 02 February 2012, 18:36:08 UTC
The low-level grep_source code will automatically load the userdiff driver to see whether a file is binary. However, when we are threaded, it will load the drivers in a non-deterministic order, handling each one as its assigned thread happens to be scheduled. Meanwhile, the attribute lookup code (which underlies the userdiff driver lookup) is optimized to handle paths in sequential order (because they tend to share the same gitattributes files). Multi-threading the lookups destroys the locality and makes this optimization less effective. We can fix this by pre-loading the userdiff driver in the main thread, before we hand off the file to a worker thread. My best-of-five for "git grep foo" on the linux-2.6 repository went from: real 0m0.391s user 0m1.708s sys 0m0.584s to: real 0m0.360s user 0m1.576s sys 0m0.572s Not a huge speedup, but it's quite easy to do. The only trick is that we shouldn't perform this optimization if "-a" was used, in which case we won't bother checking whether the files are binary at all.
