That's irrelevant. There are zillions of 100% Pure Java ways to bring any
machine to a crawl. Some are even fairly cross-platform, though others
only bring certain platforms to a crawl.

Have you done a profile of your app? This is trivial to do with the
'-Xprof' option to the 'java' command.

Even if your app is blameless, it may be doing something that triggers the
OS or JVM into this intense slowdown. That would then be evidence of a bug
in the OS or JVM. A profile may help you find exactly where vast amounts
of time are being spent. Or not. But if you are simply going to assert
that your app is blameless and non-contributory, you're never going to find
a solution, much less a cause.
