CirrusHello,
I would:
- Capture the packets using tcpdump.
- Open the captures in Wireshark. Try using Wireshark's Expert Info feature 'Analyse >> Expert Information'
- Check for any protocol anomalies: check for TCP windows size, fragmentation, tcp offload settings, etc.
- Create custom profiles for this service, so you don't disturb other VS.
- Try tuning the tcp and/or the http profiles.
- Check the routing between the clients and the F5 VS. And from the F5 to the nodes.
- You might get stuck, so worth opening a ticket with F5 and include all your investigation work.

NimbostratusHi Gus,
Thanks for your reply. Can you please guide me on how to run the tcpdump? From F5 side or client side? What is the recommended command or setup? What are the needed to check when I run the dump on wireshark? Thanks.
