[jira] [Reopened] (FLINK-23560) Performance regression on
29.07.2021
[ https://issues.apache.org/jira/browse/FLINK-23560?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Piotr Nowojski reopened FLINK-23560:
------------------------------------
The issue in
http://codespeed.dak8s.net:8000/timeline/?ben=sortedTwoInput&env=2
http://codespeed.dak8s.net:8000/timeline/?ben=sortedMultiInput&env=2
still persists. It looks like there were two different performance regressions in the same commit range. Which makes sense, because my and [~akalashnikov]'s fix for the first regression couldn't explain those {{sortedInput}} benchmarks as:
# those benchmarks are so slow (2M records/s) and involve spilling to disk, that any regression around enqueuing mailbox action shouldnt’ be visible
# those benchmarks are using FLIP-27 sources, so no problem with biased locking as described by [~akalashnikov]
