【转载】Using strace to understand a 10x Java performance improvementMar 14, 2017 • packagecloud

In this blog post, we’ll examine the UseLinuxPosixThreadCPUClocks command line flag to the JVM. Starting in a patch update of the Sun JVM 1.6, the default value of this switch was changed to true, yielding a nice performance boost, roughly 10x in our test. Users of more recent JVMs get this behavior by default, but exhuming this performance bug is interesting as it shows how strace can be useful even for Java programs.
