I am switching to a new system, because of performance issues (and because upgrading is always fun). The main things I encountered previously was Firefox getting unworkably slow at times, and the same for LibreOffice applications. I gave things more memory and vCPUs but as my current system only has 2 cores, I believe that could be the bottleneck too. I’m also using SATA in an optical drive caddy, which is not the best for speed either.
Anyways! I was wondering, would anyone have a nice idea how to determine what the bottlenecks currently are? Ideally, I would like to see that for AppVM A is using X% of the total CPU power, Y% of total RAM, limited to read/write speeds of Z Mb/s for example. I found Task Manager within Dom0, but I think I lack knowledge to interpret the data to conclude what VMs (or dom0) are running into which bottlenecks.
Please share if you have a recommended method for finding the bottlenecks and tweaking the assigned resources on your system!
