I am not sure but what if you make the variable as a volatile?
Hey i tried. But still is showing the same time for int & volatile int.
"volatile" only say to the compiler to not put the variable in a register.
Could i ask why does you want to mesure the speed of the RAM ? Is it to
study the NUMA behavior of the machine?



Thanks
Sandeep

Hi All
In performance benchmark tools, When we profile read/write timings
mostly, those read/writes are done to cache only.

I want to measure my DDR(RAM chip) performance.
So i want to make sure, every read/write should happen to DDR RAM chip
only.

How can i achieve this...Any ideas/suggestions...?
