8u171/8u172 b07 Footprint3-Jetty-* footprint regression

    XMLWordPrintable

    Details

    • Introduced In Build:
      b07
    • Introduced In Version:
    • CPU:
      x86
    • OS:
      linux, windows

      Description

      In b07 of both 8u171 and 8u172, two measures are showing a footprint regression:
          Footprint3-Jetty-G1/Linux-x86 approx -10% (~ 7.7MB)
          Footprint3-Jetty-ParGC/Win-x86 approx -7% to -10% (~ 6.3 to 8.5MB)
          
      The regression holds into 8u172-b08.

      We DO NOT see the regression in either 10.0.1 b6 or b7.

      The regression reproduces in:
      • Triage (ie, re-run on the same machine)
      • Re-triage (ie, run on a different machine)

      JVMswap results indicate the cause is in the JDK (not the JVM).
