Re: RDP performance
Ok... those specs you provide seems more than sufficient! on the server side it shouldn't be a problem, I've heard about 1cpu and 4gb ram for 10 clients without issues (guacamole server) by your last comment it definitely looks like client (en user) problem... Chrome I guess??? I've never had that problem but I usually don't use several chrome tabs on different guacamole sessions... I however did felt 1.4 version a bit slower than 1.3 Also you may want to look at your firewall in case you have one (Fortinet, Sonicwall) Guacamole over linux???

You'll need to gather some metrics across the environment to see where it's falling down. Looks at performance of the systems, also at network characteristics between the various components. Something is definitely off, there. If mstsc directly to the system performs better than Guacamole, it sounds like maybe the Guacamole server is "further" network-wise from the RDP server than your client is. But that's just a guess. -Nick > >

the performance-issue is mostly only when dragging widows and it does't really take or give much if I disable "Show window content while dragging". ‐‐‐ Original Message ‐‐‐ International Security Providers schrieb am Dienstag, 18.

RDP performance
is there a way to tune Guacamole for better performance with RDP? I only use it with 2 users currently.. and it already lags after some time and is never as snappy as connecting using mstsc. the gucamole-vm is also already quite loaded with ressources.. it's running directly on ssd, has 12gb ram and 12 cpu cores..

Re: RDP Performance Advice
Tell us about your Guacamole system specifications? How many CPUS How much RAM allocated How many network cards Did you install the hypervisor tools on the guest VMs What are the specs on your host server (Dell, HP, Microserver) Number of sockets, cores and threads How much Ram installed at what speeds What raid level are you running on the server Are the server hard drives SSD or Spindle, if spindle what RPMs What Virtualization technology are using at what version level. (RedHat KVM, Debian Qemu, VMware ESXi, Azure aka Hyper-v or Xenserver/Xendesktop aka Hypervisor) And why are you allocating so much ram to the Windows VM? Adjust the paging file system to static values to 8G (this will stop crazy disk seek) and use 16G of ram for any type of rendering, you have a nice graphics card to handle the load.

RDP Performance Advice
Hello everyone! I am looking for some advice as I have been investigating ways to improve user experience for our folks, we recently received a report of lag in a certain use-case. I have spun up my own test environment, replicating what is in the field (additional details below). Essentially what I am experiencing is the more that is changing on the screen, the higher the CPU load is on the guacd process. Once we see the guacd process's CPU hit 100%, the experience degrades significantly (no surprise there, something has to give...) Basically what the user is doing, is working with medical imaging to inspect the anatomy in a three dimensional viewport which takes up about 40% of the screen (1920x1080). The user has the ability to turn on animation for this viewport and that is when the "lag" quite noticeable. The user has a crosshair that can be rotated and dragged around the image, which becomes really difficult to use. Here's a bit of environmental detail to convey the test I am currently conducting, to recreate the issue that was reported to me: * The Guacamole Guest/VM: * is running Debian 10 OS * is running inside a KVM backed virtual environment * has four CPU cores with a 2.1GHz clock speed * has 2GB RAM * is using NGINX as a reverse proxy for TLS support * The Windows Guest/VM: * is running Windows Server 2019 * is in the same Host as the Guacamole Guest VM * is backed by a Tesla T4 GPU with Nvidia GRID drivers installed * has 8vCPU at 2.1GHz * has 64GB RAM What I've read so far is that guacd is doing some encoding which is why the CPU resource is being used up. So, I'm wondering what options may be available to try and smooth this out, if any? I have tried to make some changes to the RDP configuration ( H264, compression levels, etc...), remove NGINX and go with port 8080 directly and also to consume Guacamole from within the Host itself by adding a third guest (remove any potential LAN issues). Anyways, I appreciate any feedback, ideas or can provide more details if needed! Thanks very much, Ryan

Guacamole 1.1.0 RDP performance tweaks
Hello, Are there performance tweaks to be done to Guacamole that would help improve RDP? We've noticed that RDP is working but it a bit slower than we would like to experience. We realize this is RDP over a browser but still wanted to check and see if there is something we can do on our Guacamole server that may improve the RDP experience. Thank you.
