Hi I have some employees that use a remote application launched by a rdp file that opens a remote chrome application on the client side, I have been noticing a delay when clicking and typing on the remote app, and after making many changes on Computers I started debugging on my firewall a USG-300 Zywall.
Packet captures shows a lot of Spurious retransmissions and the behavior is recurrent and always happening, pretty much 99% of this spurious retransmissions are sent by the remote host 22.214.171.124 and I cannot see any change with many tests I have made no luck or service enhancement, So I think must be something on the server application.
Has anybody fixed this? or now how to,? thanks a lot

Spurious retransmissions are packets that are sent again even though their content has already been ACKed. That usually means that you're capturing on the receiving end of the connection, seeing data arrive twice and most likely means that the acknowledge packets for those data packets have been lost on the way to the sender. That way the sender thinks the data never arrived and sends it again.
If possible, capture on both ends to compare what packets are seen on each of the locations, and determine to point of packet loss from there.
