Description
Modern Linux kernels (>= 2.6) support the epoll(4) facility, which like the
/dev/poll facility on Solaris is a much more scalable version of the classic
poll(2) kernel call.  For better performance the default selector provider on
Linux should use epoll whenever possible.
Comments
EVALUATION -- The epoll SelectorProvider has also been added to 5.0 update 9. It is not enabled by default and requires that the system property java.nio.channels.spi.SelectorProvider be set to sun.nio.ch.EPollSelectorProvider to enable it.
