Subject: Re: [PATCH v1 1/4] fastindex: speed up index load through parallelization
Date: Mon, 20 Nov 2017 09:01:45 -0500 [thread overview]
Message-ID: <92b0b0ff-6878-003a-b26f-3b4c2c857be3@gmail.com> (raw)
In-Reply-To: <xmqq1sl017dw.fsf@gitster.mtv.corp.google.com>
Further testing has revealed that switching from the regular heap to a
refactored version of the mem_pool in fast-import.c produces similar
gains as parallelizing do_index_load(). This appears to be a much
simpler patch for similar gains so we will be pursuing that path.
Combining the two patches resulted in a further 25% reduction of
do_index_load() but with index load times getting smaller, that only
resulted in a 3% improvement in total git command time. Given the
greater complexity of this patch, we've decided to put it on hold for
now. We'll keep it in our back pocket in case we need it in the future.
