But if you compare data transfer speed of an IDE 33 rotating hard disk against a SATA (or better Nvme) SSD, and then, once data is transferred from storage you managed it in what amount of (much slower) RAM (at the most in 8 Mb in Win 3.x times, probably 48 or 96 Mb with win 9x, 128 or 256 Mb on NT 4.00 or 2K, while nowadays it is 4/8/16 Gb) and on a single core processor, running at 100-1000 Mhz, while nowadays you have likely minimum 4 cores runnning at 3,000 or something like that.
Sure you had splash screens, the sheer fact that you could open a spreeadsheet amd make some calculations (often with automatic calculation disabled and thus pressing F9 manually to re-calculate) was (IMHO) a miracle in Windows 3.x times.
This is a pet peeve of mine but today developers should be (only for testing their programs) be given the lowest powered machines available, connected to the same (shitty) internet connection a large part of the future users of the programs actually experience and see directly why their programs/tools/websites/whatever are laggish/slowish for their customers.
