Micros-Crypto performance regressions in 12+6 need investigation

    XMLWordPrintable

    Details

      Description

      There are noticeable performance regressions on both Linux and Windows that need to be investigated. They are each AES related:

      • micro.benchmarks.crypto.small.AESBench.decrypt-algorithm:AES_CBC_NoPadding-dataSize:1024-keyLength:128-provider:
            LXS: approx. -18%
            WXS: approx. -3%

      • micro.benchmarks.crypto.small.AESBench.decrypt-algorithm:AES_ECB_NoPadding-dataSize:1024-keyLength:128-provider:
            LXS: approx. -8%
            WXS: approx. -4%

      • micro.benchmarks.crypto.small.AESGCMBench.decrypt-algorithm:AES_GCM_NoPadding-dataSize:1024-keyLength:128-provider:
            LXS: approx. -3%
            WXS: approx. -2%

      The regressions reproduce when ran on the same machine (ie, triage).
      The regressions reproduce when ran on a different machine (ie, re-traige).
      A JVMswap run indicates the cause is in the JDK (ie, not the JVM).
