using macro TIMER.
** Describe the issue **
Measurements using timer do not provide the listed performance.
I measured it twice, and both times the performance was lower than stated.
Performance is particularly low when num=1 for the first time.
** To Reproduce **
export ROOTFS=xilinx-versal-common-v2022.1/rootfs.ext4
export IMAGE=xilinx-versal-common-v2022.1/Image
. xilinx-versal-common-v2022.1/environment-setup-cortexa72-cortexa53-xilinx-linux
make package TARGET=hw
cd sw
gedit Makefile &
