2-4% regression in AES-GCM decrypt and encrypt micro benchmarks on SPARC

    Details

    • Subcomponent:
    • Introduced In Build:
      b04
    • Introduced In Version:
      11
    • CPU:
      sparc_64
    • OS:
      solaris_11

      Description

      11-b4 is showing a 2-4% performance regression on Solaris/SPARC in the AES-GCM encrypt/decrypt microbenchmarks:

      • micro.benchmarks.crypto.small.AESGCMBench.decrypt-algorithm:AES_GCM_NoPadding-dataSize:1024-keyLength:128-provider
      • micro.benchmarks.crypto.small.AESGCMBench.encrypt-algorithm:AES_GCM_NoPadding-dataSize:1024-keyLength:128-provider

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

      JVMswap results are inconclusive (ie, about half the regression is recovered). Hard to say if the cause is in the JVM , the JDK, or both.
