Anyone can watch this video [1] to see how long it actually took to boot up or launch Word. But bootup seems to take 20 seconds, and launching Word took 7 seconds. Which roughly matches my memory.
So about an order of magnitude slower than you're describing. (The SE/30 had a clock speed twice that of the SE, but launching things is mostly bound by the hard drive speed.)
Other things like saving a 3-line Word document took 6 seconds. Quitting Word took 6 seconds. Basically, everything was pretty slow back then.
In contrast, I just tried launching Word on my M1 MacBook, and it took about three quarters of a second. While saving a file is simply instantaneous, as is quitting. And launching Photoshop takes 7 seconds.
Edit: here's another video [2] opening Photoshop 2 which takes a full 28 seconds.
