Hi everyone, I want to provide an update on the benchmark results that I have been working on. After spending some time preparing the environment and adjusting the benchmark script, I finally got a comparison between release 1.18 (commit: 2aeb99804ba[1]) and the commit before the old codespeed server went down (commit: 6d62f9918ea[2]) on openjdk8. The report is attached[3]. Note that the test has only run once on jdk8, so the impact of single-test fluctuations is not ruled out. Additionally, I have noticed some significant fluctuations in specific tests when reviewing previous benchmark scores, which I have also noted in the report. Taking all of these factors into consideration, I think there is no obvious regression in release 1.18 *for now*. More tests including the one on openjdk11 are on the way. Hope it does not delay the release procedure.
Please let me know if you have any concerns.
