Mac Mini performance

I was thinking about getting a cheap mac mini for the sufferfest and see that the min spec is late 2010 so if i was to get a mid 2011 Macmini5,1; Macmini5,2 running High Sierra 10.13.6.

What do i expect to see from it , will it run smoothy or will it struggle and with further updates coming I guess it may slow down even more?

Any thoughts or real life experience?

I think you’ll be OK. I’m running the app with no problems on a MacBook (Retina, 12-inch, Early 2016), which seems to have a slower CPU than the 2011 Mac Mini.

I just upgraded to Big Sur, and things are still working OK for me.
