I'm very confused. I installed OS 9.1 on my iBook (specs in sig), and it runs like an absolute dog. Granted, I'm not intending doing anything much with it, just playing a few games I found, but I'm still totally horrified by its perfomance: it takes longer than Tiger to start-up, and once it does it's hardly what I'd call "nippy". It randomly freezes whilst doing things, then eventually reawakens with no explanation of what it was doing (and no apparent task achieved).
Now, the last Classic Mac OS I used was one of the 7s on a Performa, back in my school days, and I don't remember it being this bad. Am I suffering from a borked install (very likely--I had to hatchet it using an iMac G3 restore CD), or is it just that OS 9.1 is a genuinely poor operating system? Because from what I've seen, I really cannot fathom the fanatical support it receives from some; OSX is not perfect by any means, but it's light-years ahead of OS 9...
