Not only that, but complaining about how long it takes to boot (how often
do you boot anyway? The last time I rebooted was about 6 months ago, and
my box rebooted itself because of a power glitch, and I decided to upgrade
to 8.1 then too). And complaining about how long programs take to start up
isn't really a good measure of performance.

That can be an issue. Newer systems (athlon) have the cache on the chip
anyway - mine's an Athlon with 128k or so of on-chip cache and I don't
know if there is any level-2 cache although I suspect there is. It's an
ASUS A7V 133 board, with 256 megs of RAM.

>From what I've read, linux does slow down if there isn't sufficient 
cache, because parts of the memory are left uncached - and I'm not sure
why this is - I figure the kernel should be loaded towards the bottom of
memory (in a cached region, naturally) and not somewhere where the RAM isn't
cached. Thus, the system need only suffer slowdowns when your resident set of
processes are larger than the amount of RAM that can be cached. However, it
doesn't appear this is the case -- unless more recent kernels have made this
a moot point.

Secondly, I think the issue is related to not having enough cache tag bits
rather than the amount of cache.
