Jetson nano is too slow

The os is running too slow it may take from 5 to 10 minutes to perform a single task or launch a file that is really annoying me
I am using sd card image,
Power supply 5v 3A and there is no voltage drop it supply 5.35v exactly and
I am using 64GB micro sd card kingeston uhc-1

I don’t know where is the problem exactly but i can’t do anything on it really ??
