             Summary: Increased Memory footprint in recent builds
                 Key: WFLY-7729
                 URL: https://issues.jboss.org/browse/WFLY-7729
             Project: WildFly
          Issue Type: Bug
          Components: Server
    Affects Versions: 11.0.0.Alpha1
            Reporter: Tomaz Cerar
            Assignee: Tomaz Cerar
            Priority: Critical


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.
