--------------------------------------------

Just noticed it happened also e.g. here [https://ci-hadoop.apache.org/blue/organizations/jenkins/zookeeper-precommit-github-pr/detail/PR-1594/1/pipeline]

So it's not just me :)

> This test sometimes fails on a laptop. Timed performance tests in unit tests can be problematic in general due to the variety of hardware it might run on, but I have a little fix that reduces the test overhead and tightens the timing, so it's a good first step (and works for me).
