Rasperry Zero slows down

[Landixus]

I have the problem, that my "pi zero wh" slows down and not react fast enough.
Can you tell please, which raspberry software version you are using?

Good question - I think it was just the standard Raspbian image from Dec 2016 (Wheezy?) when I got my Pi Zero.

That said, running vpower should be not at all demanding - what signs are you seeing that it is not reacting fast enough?

may be its not vpower what slows it down.
When i change my gears, it have hickups and jump from 2 to 4 for example.
With a raspberry pi 3b+ i have not the problems.

I have a speedmeter for it:

meanwhile i have the pi3b+ on battery power. I think i just stay on the pi3b+
