So, I would like test the performance of my notebook, developing one or two utilities, and have a better
mensurement about the speed.
But it can help all of us.
1st: I would like mensure the speed making a counter (exacly bogomips? may be). Loop+counter during 1 tickrate.

2nd: The most interesting: How many memory cells in ram can we access during 1tickrate? How could we develop this?!
Both utils may run in long mode (64bits). Well, in real mode too; so, we can compare the speed in the two modes!
Some one knows how to develop a very small program/routine about that?!
For the 2nd situation, a simple idea wrote in codesnipet form (consider the intention, not the sintax! there are bugs! I know. Intel syntax.)
dw the_counter_cell 0
lea bx, the_counter_cell
xor bx,bx
label:
inc [bx] # Could not be so simple like this, because the address can be cached. Right?
loop label # breaked by an interruption. Just to express the intention.
How could we create a small code for the 2nd situation, tring to force the processor to not use the cache?
Regards.
Peace out.
