Hi, We encountered performance issues for shared RDP connection with 150+ users on the same connection. We have a custom guacamole application that consists of multiple docker glyptodon/guacd:2.8.1 (we intend to align and use latest guacamole/guacd:1.4), multiple guacamole-common:1.4 proxy servers, and guacamole-client:1.2. We have a scenario with a shared RDP connection, where only one user (presenter) has write privileges and others only read only. We've been using this setup for years without a problem with shared connections with up to 100 users, and only recently have we encountered performance problems for shared connection with 150+ users. We monitored the underlying AWS ec2 machines' resource usage (CPU, memory, network), and it does not appear that the resource usage is out of the baseline, so it does not look like the problem originates in the resource usage. On the shared connection, the user with the write privileges presents some desktop application, nothing graphical, CPU, or network heavy. The network connection for the presenter seems stable. And yet, the presenter experiences significant lag on every action - clicks, cursor movement, etc. Could there be a performance limit for the maximum number of users per shared connection? We intend to execute a load test to confirm, but maybe there are other directions that we should look at?
