William Burns commented on ISPN-6580:
-------------------------------------
Also I have a protoype that adds a local executor but it didn't give me the same
performance for gets I got when I completely disabled the execution group. It gave quite
a bit better performance than the current version though.
I will look into it further tomorrow.
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.
