What’s New

  • Three Multi-Tiering command-line options are now product options. Setting them no longer requires -XX:+UnlockExperimentalVMOptions.

    Command-Line Option Description Default

    -XX:MultiTieringSamplingIntervalMS=<value in milliseconds>

    The interval at which Multi-Tiering samples methods. Tune this to control the CPU cost of sampling.

    60000

    -XX:MultiTieringSamplingStartDelayMS=<value in milliseconds>

    The delay before Multi-Tiering starts sampling. Increase this to skip the early startup window.

    0

    -XX:FalconMidTierOptimizationLevel=<level>

    The Falcon optimization level used for mid-tier compilation, trading mid-tier compile cost against code quality.

    0

    Multi-Tiering remains disabled by default. Enable it with -XX:+UseMultiTiering. See Using Multiple Compiler Tiers.
