[jboss-jira] [JBoss JIRA] (WFLY-7728) Increased Memory footprint in recent builds

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-7728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13337455#comment-13337455 ] 

Stuart Douglas commented on WFLY-7728:
--------------------------------------

It looks like there is a lot of memory (~1mb)  used up in the shared TLD descriptions, which AFAIK are not used anywhere. We could probably not parse any descriptions and just discard them (for both shared and non shared TLD's).

> In our test scenario (see below) memory footprint has been increased between EAP 7.0.0.GA and current EAP 7.1.0.DR7 for more than 8% (~8MB) for Full profile and more than 9% (~6.5MB) for web profile. Could you please comment whether this is intended.
> Test scenario:
> # Start EAP instance.
> # Measure its memory footprint - try to get the lowest possible footprint, that means force garbage collection a few times right before measuring. We enforce GC 10 times.
> We see an increase both in heap size (~ 29 vs. 34 MB) and the metaspace size (~ 64 vs. 68 MB) - these numbers are for standalone-full profile.
