Subject [jira] [Commented] (INFRA-10483) Too slow Jenkins CI agent crashes entire build process
Date Thu, 24 Sep 2015 00:08:04 GMT

    [ https://issues.apache.org/jira/browse/INFRA-10483?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14905559#comment-14905559

Tibor Digana commented on INFRA-10483:
--------------------------------------

First time I identified problem was with JVM 7 segmentation fault.
The JVM process has enough space in the Heap as I printed G summary.
So the slowdown should not be the subject to the Heap.

> The Windows build [1] permanently fails due to the machine suddenly has slow down. Maybe
one month ago the machine was pretty fast and our performance tests did not fail at all. Now
the tests are slower and do not pass.
> Interesting thing is with Windows1 which has 2 processors and somehow got slow. After
I changed JVM GC to CMS all was slower. After using Parallel GC it was better but still slower
than one month ago. So I let it be without specifying any GC algorithm and the machine is
still too slow.
