Dear reader,

I have a class X that has a (possibly) heavy array of data S as a member. A method f of X makes use of a foreach loop over taskPool(some_other_array Y).
The thing is that when I increase the length of S, linux/top shows me that my D program only uses 10% of my cpu capacity. This percentage varies with the length of S. From my perspective, S has nothing to do with X.f. Can someone please explain what might be the issue here?

regards, Chris

Can you post any of the code itself? My guess would be that something is being cached by the processor - is the code itself faster or slower when the cpu changes?

If the memory is too large, needing to be swapped to and from disk, then your program may be waiting for I/O instead of doing actual work.
