------------------------------------------------
Thanks for raising this. I just hard coded to 512 * 1024 bytes. I could see
some improvement in the final latency. Say ~9%.
the PE latency changed from 1076 secs to 970 secs.
But I need to check if this is consistent. Sorry I forgot to update the
findings as got busy with something else.
Can I take this up JIRA?

> The default ByteBuf size is 256B which is too small.
