object needs to be serialized into some form and we need some space to<br>
do that. We can't write byte by byte during serialization because it<br>
will be very slow.<br>
<br>
If you want to reduce the cost of buffer allocation, you might want to<br>
pool it, but you have to be careful about concurrency issues.<br>
<br>
PooledChannelBuffer buf = pool.acquire();<br>
...<br>
ch.write(buf).addListener(new ChannelFutureListener() {<br>
void operationComplete(...) {<br>
buf.release();<br>
}<br>
});<br>
<br>
Actually, I think this could be part of Netty! :-)<br>
