</div>I doubt it will improve performance significantly, and that's why I<br>
didn't put such feature to Netty. If you really want to do that, you could:<br>
<br>
1) Copy ChannelEventRunnable and modify run() method to call<br>
ctx.sendDownstream() instead of sendUpstream().<br>
2) Call executor.execute(new ChannelEventRunnable2(evt)) in<br>
handleDownstream():<br>
<br>
public void handleDownstream(ctx, e) {<br>
executor.execute(new ChannelEventRunnable2(evt));<br>
}<br>
