Subject: [Qemu-devel] [PATCH v1 3/3] .travis.yml: make -j3
Date: Tue, 22 Mar 2016 12:53:15 +0000 [thread overview]
Message-ID: <1458651195-21176-4-git-send-email-alex.bennee@linaro.org> (raw)
In-Reply-To: <1458651195-21176-1-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.
