You can't compare the times of running tinymembench. That's because
the amount of work they do may differ! The number of repeats for each
individual test increases if they are poorly reproducible. The test
results may be poorly reproducible if you have some other background
activity in the system.
To sum it up: just look at the numbers in the log and don't try to
time the whole program.
And some random advices for getting more stable test environment
with better reproducible results:
1. Ensure that both systems are configured to use exactly the
same screen resolution. Or blank the display to disable
framebuffer scanout by running:
"echo 1 > /sys/devices/platform/disp/graphics/fb0/blank"
"echo 1 > /sys/devices/platform/disp/graphics/fb1/blank"
2. Check for any possible IRQ spam in /proc/interrupts
3. Run the benchmark as the init process to make sure that
nothing else is interfering
