Add armv7 to age builds #198

Closed katanacrimson closed 3 years ago

katanacrimson commented 3 years ago

armv7 is currently used in the raspberry pi 4 series to an extent; while its hardware supports arm64 (to my knowledge), distribution support is not yet complete. having armv7 distributions also available will better support low-power hardware like the pi4 better.

as a side-effect, the arm version needs to also be distinguished in the artifact name. resulting artifacts would now be named "armv6" or "armv7" instead of just "arm".

Oh I'd love to see this merged, my raspberry PI is awaiting for me to share secrets with it! ;o)

FiloSottile commented 3 years ago

Is there a meaningful performance difference between the armv6 and the armv7 builds?

katanacrimson commented 3 years ago

I don't have any particular stats ready offhand. Any suggestions for a computationally stressful operation w/in age to use to compare? I've got a sample size of 4 pi 4Bs in my cluster that I can run against.

FiloSottile commented 3 years ago

Encrypting and decrypting a 100MB file with 20 recipients should give a good empiric benchmark. For decryption use the identity for the last recipient, so that they all have to be tried first.

katanacrimson commented 3 years ago

Sounds good to me. Let me see what I can throw together. How's a sample size of 100 each sound?

katanacrimson commented 3 years ago

Presuming 100 samples, but it's going to work out more like 400; I'm going to run this benchmark against my pi cluster, which is 4 Pi4Bs.

Should work out something like:

--- pi01 pi02 pi03 pi04
armv6 100 100 100 100
armv7 100 100 100 100

Variables I really can't account for at this time are going to be:

Pretty sure I never dropped haveged on these guys as a direct package, but if it is on there, it's going to be on all of them due to them being collectively managed via ansible.

Probably going to take a bit to pull all the data together, but once I do I'll slap down the analysis and benchmark script together.

age was compiled from commit 56a3f8cce3dc18e60877c6bd04068a585b0922bc - or the HEAD of this PR's branch, using ubuntu:20.04 running within WSL2.

Compile command:

docker run --rm -v "$PWD":/mnt -w /mnt -e GOOS=linux -e GOARCH=arm -e GOARM=6 golang:1.15 go build -o . ./cmd/...

Closing for now, but happy to reopen if the benchmarking numbers suggest there is a significant difference.
