Java IO Faster Than NIO

Posted by kdawson on Tuesday July 27, 2010 @08:26AM from the question-conventional-wisdom dept.

rsk writes "Paul Tyma, the man behind Mailinator, has put together an excellent performance analysis comparing old-school synchronous programming (java.io.*) to Java's asynchronous programming (java.nio.*) — showing a consistent 25% performance deficiency with the asynchronous code. As it turns out, old-style blocking I/O with modern threading libraries like Linux NPTL and multi-core machines gives you idle-thread and non-contending thread management for an extremely low cost; less than it takes to switch-and-restore connection state constantly with a selector approach."

I meant to say java io is not particularly hard to use. I personally find nio harder to use. Does anyone know how to disable the touch pad on a Sony VIAO running Ubuntu? Just disabling the device from System->Preferences doesn't seem to work.

Bash still wins: unzip, strip, touch, finger, grep, mount, fsck, more, yes, fsck, fsck, fsck, umount, sleep.
