Thanks Iris. The four tests you refer to exercise a number of the Direct*Buffer* classes. Is there anything similar for the Heap*Buffer* and ByteBufferAs*Buffer classes? :) David iris -Original Message- From: Mark Reinhold Sent: Tuesday, November 01, 2011 8:48 PM To: David Holmes Cc: nio-disc...@openjdk.java.net; core-libs-dev@openjdk.java.net Subject: Re: Benchmarks for NIO buffer performance 2011/11/1 17:07 -0700, david.hol...@oracle.com: I'm looking into refactoring all the generated buffer classes to reduce the number of classes created.
