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 https://github.com/glyptodon 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etc.., you may have outdated VNC library on your guacamole server.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:
https://guacamole.incubator.apache.org/doc/gug/installing-guacamole.html#required-dependencies

Hi,
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)
