this is a surley not the ideal way to do parsing of a message , can you<br>
suplly us with a better way that doesn't involve allocation of bytebuffer<br>

<div>Or consider making your code speak ChannelBuffers (<span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; ">parseMessage)</span></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

2. what do you recommened about tuning the netty to work with large number<br>
of Clients - one server<br>
with a average message length of 1000B wuth a high volume of messages per<br>
second (aroung 40-50K)<br></blockquote><div><br></div><div>I don't have any specific suggestions other than to equip yourself with a good Java profiler. I've personally used JProfiler to hunt down performance problems.</div>

2.a) should we have one instance of ExeuterHandler per all the channels or<br>
should we create a new instance for every channel)<br></blockquote><div><br></div><div>You can use the same instance.

2.b) should the executerHandler should use one instance of ThreadExecuter or<br>
a new one for each channel.<br></blockquote><div><br></div><div>That depends on your use-case. If you are using the same ThreadPoolExecutor for all your channels they will share it.</div><div>This is probably what you want. You should also take a look at the OrderedMemoryAwareThreadPoolExecutor instead of MemoryAwareThreadPoolExecutor.</div>
