Java IO Faster Than NIO

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."

.COM languages? You mean a web language? You do realize Perl was written as a replacement for sed, awk and the shell languages (csh, bash, etc.), to make systems administration easier by providing a single language that used a familiar, C-like syntax and made text parsing trivial. The web was a non-entity when Perl was created. The fact that it was an acceptable language for web development is tied to the initial design goal of parsing text quickly, but that was never the purpose of Perl, and the spread of the language was not solely (and not even primarily) due to its use on the web.
