Have you got proof of that and can provide figures? Having been
running it on Arm and IoT by default for a few releases now it
certainly doesn't cause fragmentation, it's allocated early in the
boot process so it's one single block. I also run zram on my laptop
and it's generally faster as when it has to hit swap that's backed by
RAM and is an order of magnitude faster, even with dealing with
compression, than hitting my NVME SSD.
