Hotrod performance regressions after ISPN-5342 ISPN-6545 -------------------------------------------------------- Key: ISPN-6580 URL: https://issues.jboss.org/browse/ISPN-6580 Project: Infinispan Issue Type: Bug Components: Remote Protocols, Server Reporter: Jakub Markos Assignee: William Burns Attachments: jfr_recordings.zip, pom.xml, Reproducer.java There were 2 recent regressions in hotrod performance, one between commits dd5501c5e and 628819461 and the second one between 628819461 and db0890270. I didn't look for the exact commits, so the name of the issue might not be 100% exact... It is easily reproducable locally with a single server instance, reproducer attached. The numbers on my machine: ||Build commit||Puts time||Gets time|| |dd5501c5e|21|74| |628819461|26|102| |db0890270|48|224| The JFR recordings (attached, captured is only the part of the test with gets) for db0890270 show a lot of time is spent in HotRodDecoder#resetNow(), and also the allocation rate goes from 100MB/s for dd5501c5e to over 1GB/s for db0890270. There are no glaring differences between dd5501c5e and 628819461.
