First, let me be clear: I am a fan of powerd++.
I use it on all servers in the basement.
A recent test shows my gateway does not benefit from it.
To determine the range of this graph, I consulted my logs:

Running powerd++
Here is a graph with powerd++ not running:
Without powerd++ not running
This morning I created this graph with the same time period, but days later.
Running from the command line
This is a short run:

That drops the frequency, clearly.
So…
The gateway runs slow enough as it is. It won’t benefit from powerd++ at all.
