Apr 28, 2009F5 and NetTcpBinding (WCF)
I have WCF service, which uses NetTcpBinding.
If I by-pass F5 and directly go to Application server, the response is much faster.
But if I use F5 (Virtual IP) to route my request to one of the application server, then there is significant time delay (close to 1000 millisecond).
Any ideas?

What kind of virtual server do you have defined to pass the traffic? Can you post an anonymized copy of the config by running 'b VIP_NAME list'? If you capture a tcpdump of the client and server side traffic, where is the latency being introduced? You can get tips for using tcpdump by searching for this term on AskF5.com. - AA_2646

Aaron, what you asked is difficult for me to get, as I work for application development and do not have any control over network administration. - hoolio

I think you'll need to have someone who has admin access to the BIG-IP help troubleshoot the issue with you. - JC_41688

I think that message is just from tcpdump because the snaplength (length of the packet to capture) was smaller than the packets being sent (Click here -> Click here). You can add a -s 0 flag to the tcpdump command to capture the full packet size. In general, you can try searching AskF5.com for error messages you see on an F5 product. If you don't find anything there, try a search engine as it might be a non-F5 component. - JC_41688
