Memory bandwidth usage

Question

How do you calculate the used memory bandwidth (RAM)? What performance counters are needed?

I came across a tool that could do this, the “Rightmark multi-threaded memory test”. But, unlike other Rightmark tests, I did not find the source code for it, only binary files

Answer 1

It is very difficult to "calculate" the use of memory bandwidth. There are many nontrivial caches and problems with MMUs. The only real way to do this is either through simulation or through real measurements.
