That particular benchmark, as some others, exhibit relatively high run-to-run variance. I have run it again many more times to average-out the variance, and I'm now getting the following results: baseline: 3503.844 ms/ops, fast-locking: 3546.344 ms/ops, percent: -1.20% That is still a slight regression, but with more confidence. Regarding Lilliput, I cannot really say at the moment. Some workloads are actually regressing with Lilliput, presumably because they are sensitive on the performance of loading the Klass* out of objects, and that is currently more complex in Lilliput (because it needs to coordinate with monitor locking). FinagleHttp seems to be one of those workloads. I am working to get rid of this limitation, and then I can be more specific. ------------- PR: https://git.openjdk.org/jdk/pull/10590
