He has a good point about the access time. The thing of it is that the current state is about the same as scsi (flame bait). And at a more reasonable price. if the hdparm's are optimize it may make a difference, and bios settings may help (auto, LBA, etc). If the ide interface is UDMA 66/100 capable that also helps (but not as much as the industry would have one believe). 7200rpms aint bad. Swap access is also a consideration. Cheers.

Recompiling the Linux kernel seems to take longer than I would expect. I've switched from a 233MHz processor to an 850MHz one, but the process doesn't seem to be going even twice as fast. So I'm wondering what's the most likely limiting factor in my system. The critical parameters:
850MHz Athlon Tyan S2390 motherboard 256MB PC100 memory 30GB 7200 RPM hard drive
I assume that nothing else is likely to be relevant.
Two factors (assuming the rest of the system is equal):
HDD access time - compiling the kernel takes *lots* of disk accesses - Once you get a reasonably fast CPU in your motherboard, the disk access time starts to be the limiting factor.
Does that have a straightforward relation to rotation speed? What's about the best access time one can get these days at a reasonable cost?
FSB speed (the speed at which the CPU talks to the motherboard). There is a limit to the speed at which data can get in and out of the CPU. Without upgrading this, your CPU will be sitting around waiting for data.
How would one upgrade that?
