while im afraid to use my 1400 due to its hinges possibly failing in 9
months my 13.3in PDQ Wallstreet 266 with 128mb of ram and a 4GB
rotational IDE hard disk has held out since i got it in august 2023 and
ive always used 8.1 on it for you system 7 users out there is there a
massive difference in speed between running 8.1 on a G3 and running
7.6.1 on a G3-upgraded mac? i would think that 8.1 would be faster due
to more PowerPC code maybe im wrong?

I can't say for certain, but usually newer versions of the OS run
slower on the same hardware due to the extras added to the system
software, much of it often just useless gimmicks and eye candy.

Well, that's the official saying: More PPC-code = faster.

From my personal experience, nothing beats System 7.1.2 on a first generation NuBus PowerMac. Later systems had not only more PPC code but more code
overall, which resulted in longer boot times and some overall decrease in perceived speed for everyday tasks. Also take into account that RAM transfer speed is also a contributing factor, along with possibly shared RAM for framebuffer and system contibuting to performance decrease.

The faster the CPU, the more cache it has, and the faster RAM speed is, the less apparent are differences between systems.

OS releases ≥8 might in theory be slower because of the increased eye candy, but I have not taken solid measurements.
