UI freezes at each update

[Timmmm]

On my machine if I hold down the Down key to scroll through processes, then the UI freezes for about half a second every time it gets new data. Not the smoothest experience.

It's also surprisingly slow to start - again about half a second to get to the UI, and you can see an empty UI for a bit before it gets filled it.

I would guess there's some blocking code somewhere that isn't as fast as assumed?

On my machines this generally hasn't been a big issue.
However, this is an area of the app that hasn't been optimized. I'm happy to accept an PRs that do that, I probably won't have time to look at this for a while.
