What guacd messages are you capturing? Does this mean the log messages (put guacd in trace mode and capture the trace message)? Or are you actually doing a packet capture and intercepting the Guacamole protocol messages? Or RDP/VNC protocol messages? The 150ms is being measured where, and between which two events *exaclty*? > Is the 150ms from my tests typical? Is there anything specific I can do > to reduce it?
