Try a different VNC; RealVNC or TightVNC and see if you notice any difference.

Hi Shanon,

I’m not sure about the version numbers but I cloned guacamole-client and guacamole-server
directly from about a month ago so it should be pretty recent.
The guacamole server is running on debian 8.3. The libjpeg62-turbo and libjpeg62-turbo-dev
libraries are up to date (according to apt-get)

I should probably clarify that turbovnc runs without issues, it’s only guacamole.

Welcome Alex
VNC over Guacamole should be pretty fast, especially over LAN. Near or as fast as your TurboVNC
client. Guacamole's first desktop/visual protocol was VNC after all.

Please specify what version of Guacamole you installed, on what server OS etc.., you may have
outdated VNC library on your guacamole server.  On Ubuntu thats libjpeg-turbo, for OS X Im
not sure where that is to download.

See libJPEG-turbo in required deps:

I’ve recently installed a guacamole based tool to access remote machines. In comparison
to using TurboVNC directly to the same machine, guacamole seems to perform very poorly (low
fps, regular stutters, noticeable delay between input and feedback)  and on safari some of
the colours seem to be messed up. I’m just wondering is this possibly because I’ve set
it up differently in some way to what it should be or if this is just the nature of the additional
web layer on top of vnc?

Another small issue I’ve found is that the text becomes blurry if the browser stretches
the resolution of the session. I try to set the size to be 100% (in the ctrl+alt+shit menu)
but the minus button doesn’t let me go below 118% unless I resize my browser window)
