update-index/diff-index: use core.preloadindex to improve performance
'update-index --refresh' and 'diff-index' (without --cached) don't honor the core.preloadindex setting yet. Porcelain commands using these (such as git [svn] rebase) suffer from this, especially on Windows. Use read_cache_preload to improve performance. Additionally, in builtin/diff.c, don't preload index status if we don't access the working copy (--cached). Results with msysgit on WebKit repo (2GB in 200k files): | update-index | diff-index | rebase ----------------+--------------+------------+--------- msysgit-v1.8.0 | 9.157s | 10.536s | 42.791s + preloadindex | 9.157s | 10.536s | 28.725s + this patch | 2.329s | 2.752s | 15.152s + fscache [1] | 0.731s | 1.171s | 8.877s [1] https://github.com/kblees/git/tree/kb/fscache-v3 Thanks-to: Albert Krawczyk <pro-logic@optusnet.com.au> Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Jeff King <peff@peff.net>
