Hi Stephan,
We are using tcp profile on both client and server. I have tried capturing tcpdump and i am seeing a lot of tcp window full/tcp segment of a reassembled PDU's in the dump file. Could it a buffering problem?
- Feb 13, 2015Hi Sekharchandra, the TCP payload is segmented to fit into IP datagram. That´s why you see the "segment of a reassembled PDU" information. The "TCP window full" (information from WireShark) just indicates, that the sender makes use of the allowed window size. Both is fine from my perspective. Are you seeing messages in /var/log/ltm while observing the problem? tail -f /var/log/ltm Any indication for exceeded http header size there? You can try to test with lan-optimized-tcp profile. It is using increased window sizes and ramps up faster. You can look as well after delays caused on server side. Perhaps you are using SNAT and the server tries to resolve the client IP versus a reputation list? You can also try to apply a OneConnect profile which allows KeepAlive conversion and connection pooling both on client- and serverside. Thanks, Stephan
