Subject: [PATCH 2/3] benchtests: Bump start size since smaller sizes are noisy
Date: Thu, 09 Nov 2017 05:14:00 -0000 [thread overview]
Message-ID: <1510204408-1739-3-git-send-email-siddhesh@sourceware.org> (raw)
In-Reply-To: <1510204408-1739-1-git-send-email-siddhesh@sourceware.org>
Numbers for very small sizes (< 128B) are much noisier for non-cached
benchmarks like the walk benchmarks, so don't include them.
* benchtests/bench-memcpy-walk.c (START_SIZE): Set to 128.
* benchtests/bench-memmove-walk.c (START_SIZE): Likewise.
* benchtests/bench-memset-walk.c (START_SIZE): Likewise.
