I've considered things you have suggested and report them in the rest of my email BUT the thing that baffles me is that regular file transfers that are not done through Guacamole are okay(scp around 900Mbps and guacamole around 70Mbps). I am looking for an explanation of this big difference (and hopefully a way to fix it) in the file transfer speed. To answer your questions here is my setup. 1) Guacamole is run on Ubuntu server16.04 and all other OSes are different versions of Linux (no Windows!) 2) Guacamole server is a physical machine (no VM or Container) 3) The Guacamole server has 24GB of RAM and Xmx is set to 8GB 4) The CPU has 6cores (12 threads) 5) The hard disk is SSD 6) The host is a regular PC (I think this is more than enough since most of the times CPU is idle and RAM is free) 7) The network uses CAT6 and all switch ports and NICs are 1Gbps Thanks.
