Steven Hawkins resolved TEIID-5422.
-----------------------------------
Resolution: Done
Changed the interval to 5 seconds (more than twice the default timeslice of 2 seconds)
which shows a great improvement in the performance test checked in with this issue, but no
degradation in the other performance tests.
Buffer cleaner running too often in some cases
----------------------------------------------
Key: TEIID-5422
URL:
https://issues.jboss.org/browse/TEIID-5422
Project: Teiid
Issue Type: Bug
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 11.1, 11.0.1, 10.3.3
As observed in TEIID-5418 when the buffer cleaner runs too often it causes thrashing by
pushing out pages that get reused close to the cleaning interval of 100 milliseconds.
Increasing that interval to at least beyond the default time-slice will consume more heap
- but the cleaner will still be engaged when a processing thread must clean beyond the max
allowed.
