Hmm, so this is tied to MacOS on the client side and everything else is the same? Do you have the same connection type for all the x2go sessions? One thing you could try: run x11vnc within the x2go session and connect to the session via vnc. Is it also slow in vnc? Suspend the x2go session. Is anything changing in the vnc session? Note: for this test to work you must disable the sleep feature on the server. Expand the X2GO_NXOPTIONS variable /etc/x2go/x2goagent.options like this: X2GO_NXOPTIONS="sleep=0" Afterwards start a NEW session (not reconnecting to an existing one) and do the vnc test from above.
