我们做了 Alibaba Dragonwell1.8.0_372对于阿里版本是8.15.16 测试 性能没有 hotspot 1.8.0_112 好。在SciMark Java微基准测试中。

用的工具是 phornonix-test-suite。请问有什么好建议? 为什么性能没有它好。是我们使用问题还是本来就性能就是不如hotspot ?后续有啥改进计划?

我说是 和hotspot 和openjdk 对比。不是同等openjdk对比。

dragonwell-8.15.16(8u372)与oraclejdk 8u381性能结果没有显著差异。建议将jdk更新到最新版本进行测试。1.8.0_112是很老的版本

用你说版本对比测试了。俩次执行结果相反。不稳定。我在window 机器上测试的。到底拿什么工具测试比较靠谱?
