Subject: [PATCH v3 4/4] read-cache: speed up index load through parallelization
Date: Thu, 6 Sep 2018 21:03:59 +0000	[thread overview]
Message-ID: <20180906210227.54368-5-benpeart@microsoft.com> (raw)
In-Reply-To: <20180906210227.54368-1-benpeart@microsoft.com>

This patch helps address the CPU cost of loading the index by creating
multiple threads to divide the work of loading and converting the cache
entries across all available CPU cores.

It accomplishes this by having the primary thread loop across the index file
tracking the offset and (for V4 indexes) expanding the name. It creates a
thread to process each block of entries as it comes to them.

I used p0002-read-cache.sh to generate some performance data:

p0002-read-cache.sh w/100,000 files
Baseline           Thread entries
------------------------------------------
20.71(0.03+0.03)   13.93(0.04+0.04) -32.7%

p0002-read-cache.sh w/1,000,000 files
Baseline            Thread entries
-------------------------------------------
217.60(0.03+0.04)   199.00(0.00+0.10) -8.6%
