Very slow read speed on the qemu image

[Eboubaker]

I noticed massive read speed reduction (like 10-20 times) when inside qemu this makes building/pulling images take hours. Do you have any improvements that can be made here?

I tested with this script https://github.com/thodnev/MonkeyTest/blob/master/monkeytest.py inside termux i get normal 90MB/s but inside qemu i get 4MB/s. I tried my best to fix this bottlneck best i got is 10MB/s by using .raw image format instead of Qcow2
