Is page size actually a noticeable problem for most people (say, MacBook users)? Linux has supported huge pages for years, and my impression is that it's still considered a niche feature for squeezing out the last percentage of performance. I don't think any popular distro enables it by default.

If you have a large program putting its text on huge pages can make much more than one percent difference. Any time your program spends on iTLB misses can be eliminated with larger pages.

Not just Linux, but windows also has Large Pages support. Back in the day where CPU cryptocurrency mining was still a thing (and for some cryptocurrencies which are aimed towards CPU-mining still is), some mining programs would ask to enable large page support.
