OIO always slower than NIO?

[IanS]

I wanted to try OIO, since I'm typically dealing with a small number of
connections, and I am finding it to be consistently slower than NIO(~30%),
even with two hosts, and one connection each.  

Are there tuning parameters that I should to tweak to make OIO faster, or
have other people found this as well?

Specifically, I have a large number of request-response message pairs,
similar to the ping example.  I am not waiting for the response to come back
before sending another request, so there could be a large number of requests
pending at any given point in time.   

Thanks, Ian


FYI, my pipeline is:

		public ChannelPipeline getPipeline() throws Exception {
			ChannelPipeline p = pipeline();	
			
			p.addLast("frameDecoder", new LengthFieldBasedFrameDecoder(16*1048576, 0,
4, 0, 4));
			
			p.addLast("protobufDecoder", new
ProtobufDecoder(DotsProtocol.DotsMessage.getDefaultInstance()));

			p.addLast("frameEncoder", new LengthFieldPrepender(4));
			p.addLast("protobufEncoder", new ProtobufEncoder());
	
			p.addLast("streamer", new ChunkedWriteHandler());
			
			// utilize the multi-threaded execution handler.  
			if(useNio)
				p.addLast("executor", executionHandler);
			
                        p.addLast("timeout", new
IdleStateHandler(hashedTimer, 4*PING_INTERVAL, PING_INTERVAL, 0));
      
			p.addLast("handler", new DotsServerHandler());
			return p;
		}
