I think i made a mistake to do my own protocol encode and decode in
IOHandler messageReceived which is supposed to handle the business logic. It
causes my application eats up 100% CPU time when large size of incoming
message. I guess I didn't handle the decoding well.
1) Therefore, I believe the existing of codec layer is for the performance
enhancement(handled the encoding and decoding issue in codec filter, correct
me if i am wrong)
2) I read the source of SumUp example and I wonder how can I handle the
hundred of sessions in customer codec filter. For instance, if I get the
packets from one session however the packets are not complete for whole
message. Should I put that into the session.setAttribute('AlreadyGotPacket")?
and next time, just getAttribute('AlreadyGotPacket")
Thanks.
