Anyway I can see how much of my CPU cache is in use?

Sorry. Probably a silly question. I'm just curious like I am at times of how much of my system memory is in use.

Is there anyway to see how much of my CPU cache is in use? I've just upgraded my CPU to a D945 from a D830 and it has 2x2Mb cache.

Probably continuously the whole, as the recent PCs' OSes won't fit in ;)
Maybe you could find out about the rate of cache misses, if this is interesting to you.

Oh right. Well could be interesting. What's a cache miss anyway?  ::)

Simplified story: when "processor core" needs to crunch some data or execute some code, it looks into "its memory pools (a.k.a. cache)". If the data/code is there, it's called a "cache hit". If not, it must be delivered to the cache (instances) from main memory first, this case is called "cache miss".

Short story long: other can explain much better then me, see http://en.wikipedia.org/wiki/CPU_cache  ;)
