Yanfei Lei commented on FLINK-30623:
------------------------------------
For checkpointSingleInput.UNALIGNED and checkpointSingleInput.UNALIGNED_1, the
regression occurred during 13ef498172b...fb272D2cdebf. Seems to be related to
fb272D2cdebf(FLINK-30533). I submitted two benchmark requests to verify this:
* [#177|http://codespeed.dak8s.net:8080/job/flink-benchmark-request/177/]
(before FLINK-30533)
** checkpointSingleInput.UNALIGNED ： 333.635178(+-8.169488)
** checkpointSingleInput.UNALIGNED_1：213.837107(+-7.282883)
* [#178|http://codespeed.dak8s.net:8080/job/flink-benchmark-request/178/]
(after FLINK-30533)
** checkpointSingleInput.UNALIGNED ： 61.536982（+-3.581509）
** checkpointSingleInput.UNALIGNED_1：38.207438（+-2.937051）
[~lindong] could you please help take a look?
