[HttpCore] NIO FileChannel direct I/O rocks
Folks,
I finally put together an example of HttpCore NIO based HTTP server
optimized for serving static files off the disk:
https://svn.apache.org/repos/asf/jakarta/httpcomponents/httpcore/trunk/module-nio/src/examples/org/apache/http/examples/nio/NHttpFileServer.java
The code is not pretty. There are lots of instanceof checks all over the
place, but according to my (very unscientific) performance benchmarks
the use of FileChannel direct I/O seems to result in a 60% performance
improvement even for fairly small files (12K). I'll try to run a little
more systematic tests and put the results on wiki. Overall, it looks NIO
might even outperform classic I/O when used to serve static content off
the disk.
I thought some people might be interested to hear that.
Oleg
