I think there is a tendency to simply give in and buy bigger hardware if something doesn't work. With friends and family, I sometimes feel like having to talk them off the roof with regards to pulling the trigger on really expensive (relative to the tasks they're doing) hardware, simply because performance is often abysmal due to the fact that they trashed their OS with malware and bloatware and whatnot and can't understand all of that.

It's the same at work, to some degree. Our in-house ERP software performs like kicking a sack of rocks down a hill. I don't know how often I had to show devs that the hardware is actually idle and they're mostly derailing themselves with DB table locks, GC issues and whatnot. If I weren't pushing back, we probably would have bought the biggest VMs just to let them sit idle.
