Android performance lower than iOS performance

[krzysztof-chwiolka]

I have been running our performance metrics and I noticed a large discrepancy in the performance between iOS and android devices.

Android testing device: Note 8
iOS testing device iPhone 11

it took between 22/71ms for the Note 8 to draw the first frame
it took between 4/16ms for the iPhone 11 to draw the first frame
it also took around 11/24ms for the iPhone 8 to draw the first frame

This was on a block of frame at 3/5mb per output frame.

So any further optimisations on android end would be great to see.

In dc4c20e we updated the makefile and I found I was NOT applying -O3
So performance may have significantly improved re: frame copying (at least) here
