Subject: [PATCH v2] unpack-trees: avoid duplicate ODB lookups during checkout
Date: Fri, 7 Apr 2017 15:53:05 +0000 [thread overview]
Message-ID: <20170407155306.42375-1-git@jeffhostetler.com> (raw)
From: Jeff Hostetler <jeffhost@microsoft.com>
Version 2 simplifies this and just copies the tree_descriptor
data and borrows the underlying buffer without mallocing. It
also handles the n=3 cases, so merges shold be helped too.
I've updated the p0004 perf times in the commit message.
The V2 changes took ~0.15 off the V1 times. The total
reduction is ~1 second.
================
Avoid duplicate ODB lookups for trees during traverse_tree_recursive().
