At this point I'm not even sure what people mean when they say "slow" or "poor performance", since I have a mid-tier PC and have no problems with VSCode or anything else. Everything starts fast and I have no latency issues when typing. Imperceptible differences in time are not something I would ever consider a performance problem, certainly not in the case of UX.

Same thing with memory usage. If I'm not even using a third my RAM with my browser, editor and a few other random things open I'm not going to complain about something being a "resource hog".

There are two possible reasons for this.

One, you simply may not know better. If you've never experienced the typing latency of an 80s or 90s style system, you may not have a reference point for low latency. Not saying this is necessarily the case for you, but I suspect it's the case for some people.

Second, people genuinely have different perception. The most stark example of this in practice for me was the perception of flicker on CRTs. Many people claimed to just not notice flicker at 60Hz, while for me going back from 100Hz to 60Hz was unbearable for longer amounts of time. I'm sure similar differences exist with our perceptions of latency.
