I happen to have an experience with Pentium at 75 MHz, where text in Borland Pascal on DOS appeared slower than I could type (long before learning touch-typing), and pressing backspace after spotting an error required some patience.

Scrolling in GUIs is known to be sorta expensive: it's normally offloaded to the graphics system to be done wholesale as just a shift of the image, but if your GPU drivers suck then you're in for a crappy time (which was normally a thing in a fresh installation of Windows or Linux).

Basically, don't do much on a weak CPU.

I find that hard to believe. Borland IDEs ran extremely well on the 386 and 486 machines of the day. If you're having trouble with them on a Pentium you probably misconfigured something.

Wasn't my call, as it was a uni machine.

This is bullshit because DOS applications wrote to the VGA registers directly.

You mean slow scrolling in Windows/Linux due to wrong drivers is bullshit because DOS apps wrote to VGA registers?

No, scrolling under DOS was really fast. And Windows 98 run much faster than X on a machine with similar specs.
