I already ran some capture some capture like you said (see the command on the second answer). What i see is some missing packet, some duplicate ACK and some retransmission. At a time, there is 1 second between the retransmission and it represent the delay i talk about.

 

Also, this morning, i tried an exact same configuration on a VM installation with the same BiGIP version and the same application, and everything work fine.
