source of lag due to zram?



I've been experiencing random lagging with my nexus 5x and I just noticed that the stock nexus 5x kernel implements zram.
Here's screenshot:

For those that don't know, zram is basically a compressed in RAM swap space.

Everytime the kernel saves to and from zram, it has to compress/decompress the contents and that could be the source of some of the lag people are seeing.

I plan on rooting my phone as soon as I get my usb c to usb a cable and disable zram and see if that helps with the random lags that i've been experiencing.
