I don’t run Guacamole anymore, but I would suggest running the client and server on separate instances or containers, giving the instances/containers enough cpu that you don’t see spikes above 40%, and watching the memory usage and/or make sure memory isn’t maxing out. Watching the network usage and possibly using multiple nics if network bandwidth is an issue.
You need to discover the bottleneck and resolve that. If on AWS use detailed monitoring, etc. From: Sean Hulbert <shulb...@securitycentric.net.INVALID> Sent: Thursday, January 18, 2024 2:49 PM To: user@guacamole.apache.org Subject: Re: Options for hardware acceleration/vaapi for guacd Increase your CPUs to 2x6 (12Core) then increase RAM to at least 24G, then make sure your networking is at least 1G, this will help some. I would also use Window 2019 or Ubuntu with xRDP Hope this helps. CONFIDENTIALITY NOTICE: This communication with its contents may contain confidential and/or legally privileged information.

The viewing of videos is where the problem lies. A 720p sample video viewed through Guacamole is very laggy and the audio pops in/out. It is not reliable. During video playback, all other mouse movements or commands are delayed on the server as well. I see on the server side when viewing a video that a guacd process spikes to 80-100%. We are also using Docker. 1. I assume Guacamole encodes the rdp and sends it as video in some way? Is there a way to use hardware accelertation such as intel vaapi/quicksync for this process and could it maybe help? Not as video, as images. The Guacamole software/protocol does some calculations to try to choose the best image format possible, but video/visual data is transferred as images. I do not know of any hardware acceleration that is currently supported. The one thing that might help is support for GFX over RDP, which is in the master branch and should be released in the 1.6.0 release, whenever that happens (later this year). 1. 2. Is it believed Docker vs native would have any real difference in playing and streaming a video from an RDP session? I doubt this would make a difference. -Nick
