Very Slow Application performance behind F5

Now that Matt mentions it, I remember a customer who was running a Windows based app where the app was trying to do a netbios lookup of the client IP. The netbios query was failing but took a few seconds to time out. A stab in the dark, but something to check on.

 

 

Do you see the same delay if you use curl from LTM to the VIP? What about from curl to the servers directly?

 

 

I'd think you'd see a definitive gap between frames in the tcpdumps that should indicate who is sitting on the connection. Once you figure that out, you can try to figure out why.
