[parfait:master] New Comment on Issue #8 Expose metrics via REST service ( https://github.com/performancecopilot/parfait/issues/8 )
By tallpsmith ( https://github.com/tallpsmith ) :

Marking is WON'T FIX - as pmwebd within PCP would expose these naturally. It seems redundant to have this within Parfait.

#10 Document the magic JVM flag to reduce CPU contention etc ( https://github.com/performancecopilot/parfait/issues/10 )

This issue stems from the discovery many moons ago that for older Java+Linux Kernal combinations some of the Thread CPU metric collections were INSANELY SLOW.

To work around this, an evilly hidden JVM option was discovered: -XX:+UseLinuxPosixThreadCPUClocks

Which when active, drastically improved performance.
