- Performance improvements on Jenkins
XXX: intrigeri (platform optimization: [[!tails_ticket 11175]],
[[!tails_ticket 11113]])
We figured we could probably get some nice test suite performance
improvements, on our Jenkins environment, by optimizing the platform
itself.
After an initial round of benchmarking conducted in January, our
next action was to give our server more RAM in order to give us more
flexibility to evaluate different configuration options. This was
done in February, and then we went through a few optimization
cycles, identifying bottlenecks and addressing them until we were
satisfied ([[!tails_ticket 11175]], [[!tails_ticket 11113]],
<https://tails.boum.org/blueprint/hardware_for_automated_tests_take2/#benchmarks>).
As a result, we have improved our test suite runs throughput, in the
worst case scenario, from 3.3 to 8 runs per hour. This gives us room
to run more automated tests in that environment, and also shortens
the feedback loop for developers, since congestion is now less
likely to happen. We will keep an eye on metrics to confirm, in one
or two months, that real workloads indeed benefit from
these changes.
