Some of our Windows 10 64-bit desktop app users are intermittently seeing 3 seconds latency while switching channels. They click to one channel and count out loud to three (one one-thousand…) and then it switches.
We are running Mattermost 4.4.0 and on 3.7.1 desktop app. We have around 65 people using the system. Mattermost behind Nginx with PostgreSQL is deployed on a NixOS virtual machine guest on Hyper-V. I’ve allocated 2 GB of RAM and 4 processors to the VM.
htop does not show any RAM or CPU resource exhaustion during times when the latency strikes (or any other times). The load average is 0 and only 325 GB of RAM are allocated on the entire system.
Do other people seen this issue? Does anyone have suggestions for how to track down performance issues like this? Is there some logging options I could enable in mattermost or nginx to help?
