It didn't really become fast until 10.2 and even then you needed a GPU that supported Quartz Extreme to get that. My G3 Imac never ran it well because of that.

I had to disable basically every graphical effect to get anything remotely resembling speed. Mac OS 9 on the same machine even with an eighth the RAM (64MB) was way way more responsive. Unfortunately even by the time I got that machine in 2005, the OS 9 browser situation was a problem for a lot of sites.
