Yep. I suspect GP has just gotten used to this and it is the new “snappy” to them.
I see this all the time with people who have old computers.
“My computer is really fast. I have no need to upgrade”
I press cmd+tab and watch it take 5 seconds to switch to the next window.
That’s a real life interaction I had with my parents in the past month. People just don’t know what they’re missing out on if they aren’t using it daily.
Yeah, I play around with retro computers all the time. Even with IO devices that are unthinkably performant compared to storage hardware actually common at the time these machines are often dog slow. Just rendering JPEGs can be really slow.
Maybe if you're in a purely text console doing purely text things 100% in memory it can feel snappy. But the moment you do anything graphical or start working on large datasets its so incredibly slow.
I still remember trying to do photo editing on a Pentium II with a massive 64MB of RAM. Or trying to get decent resolutions scans off a scanner with a Pentium III and 128MB of RAM.
64MB is about the size of (a big) L3 cache. Today's L3 caches have a latency of 3-12ns and throughput measured in hundreds of gigabytes per second. And yet we can't manage to get responsive UIs because of tons of crud.
My modern machine running a modern OS is still way snappier while actually loading the machine and doing stuff. Sure, if I'm directly on a tty and just running vim on a small file its super fast. The same on my modern machine. Try doing a few things at once or handle some large dataset and see how well it goes.
My older computers would completely lock up when given a large task to do, often for many seconds. Scanning an image would take over the whole machine for like a minute per page! Applying a filter to an image would lock up the machine for several seconds even for a much smaller image a much simpler filter. The computer cannot even play mp3's and have a responsive word processor, if you really want to listen to music while writing a paper you better have it pass through the audio from a CD, much less think about streaming it from some remote location and have a whole encrypted TCP stream and decompression.
These days I can have lots of large tasks running at the same time and still have more responsiveness.
I have fun playing around with retro hardware and old applications, but "fast" and "responsive" are not adjectives I'd use to describe them.

The newish windows photo viewer in Win 10 is painfully slow and it renders a lower res preview first, but then the photo seems to move when the full resolution is shown. The photo viewer in windows 7 would prerender the next photo so the transition to the next one would be instant. The is for 24 megapixel photos, maybe 4mb jpegs.
So the quality has gone backwards in the process of rewriting the app into the touch friendly style. A lot of core windows apps are like that.
Note that the windows file system is much slower than the linux etx4, I don't know about Mac filesystems.
