Subject Re: [java] Message codec improvements
Date Mon, 15 Dec 2014 20:49:10 GMT
I will need to recover my old-branch to give you some pointers about it…

I - A lot of the codecs are creating plenty of intermediate objects… 

Pseudo-Example on the messageCodec:  List… decodedProperties…

Message message = new Message(list.get(0), list.get(1)… );

it could be something done directly at wire layer without requiring the intermediate object.
that’s putting some pressure at the GC.

There’s also a case now where having SASL is increasing the time response (having SASL is
requiring having an intermediate buffer I believe)… 

And there are other cases that could go beyond simply the codec.. but I have more abstract
concerns at this point.. where we could probably talk over the phone.. or have a dedicated
session over IRC.

I have this transient branch containing some of the micro-benchmarks and some proposed changes
I had a while ago. It’s probably not in a working state… but it would give you an idea
where I was aiming for.
