Well, a separate track might be a bit too much I feel ;). I'm interested
also in other things that are happening... We'll see what the program will

I'm not sure what do you exactly mean by 'cache swaps'. If you mean that
your application private cache is swapped out, then I can imagine this is a
problem but I'd need more details to tell how big.
