Subject: [Qemu-devel] [PATCH v2 3/5] .travis.yml: make -j3
Date: Wed, 23 Mar 2016 17:20:55 +0000	[thread overview]
Message-ID: <1458753657-21664-4-git-send-email-alex.bennee@linaro.org> (raw)
In-Reply-To: <1458753657-21664-1-git-send-email-alex.bennee@linaro.org>

The move from Travis VMs to Containers came with a upgrade from 1.5
cores to 2. The received wisdom is -j N+1 means a core can be doing work
while other threads wait for IO to complete. This is hard to test on the
Travis infrastructure but an initial before/after eyeballing seems to
confirm it is an improvement.
