Subject: ChaCha20Poly1305 is slow on ARM64
Date: Fri, 11 Jan 2019 00:26:06 -0500 [thread overview]

There's a note from Jason at
https://github.com/golang/go/issues/29440
https://github.com/golang/go/issues/22809
with information about the slow performance of ChaCha20Poly1305
on 64-bit Arm systems using the Go standard libraries.
In an effort to get support to remedy this problem,
it would be super helpful to have access to any
of the following:
- copies of bug reports that reference the slow or
battery inefficient behavior on arm64 devices
- some estimate of the potential benefit of improved
performance, measured in some way that's
easy to understand (% longer battery life?
% faster?)
I'm not in a position to write the better code, but
perhaps I can help get it merged.
thanks
Ed
