Have you done a packet capture when the F5 is not in the middle to see if there are any differences on the network flow?

 

Have you verify that the F5 interfaces are connection at the highest possible speed?

 

What is the NIC speed on the SQL and web servers? Do the SQL server, web servers, and all network equipment have jumbo frames enabled?

 

If the SQL and web servers have 10Gbps Ethernet and the F5 is only 1 Gbps, then things will go slower.

 

IF the SQL and web servers are configured to use jumbo frames and the network supports it, the F5 will introduce delays, as I don't believe any F5 devices support jumbo frames.
