Thought you may find these results interesting, just killed some more
latent concurrency bugs in JERI.
* Mahalo stress tests are now running with 0% contention at close to
raw socket speed.
* ClassLoading is thread confined for each classloader to avoid
contention.
* All underlying infrastructure takes advantage of modern Executors
and concurrency utils.
* TaskManager has been replaced and is no longer needed.
* There are no unnecessary DNS calls, only those required to make
connections.
* Security checks have an imperceptible impact on performance.
* RFC3986 compliant Uri class uses bitshift operations for ASCII
string manipulation.
I need someone with access to decent hardware to really test this out.
