Hi @DavidJFelix,

Thank you for this information.

I see your point, but if you don't mind could please create an MR with the appropriate change?

Hi, this is added to the arm branch for now.
https://github.com/Aleksandr-Filichkin/aws-lambda-runtimes-performance/blob/arm-lambda/go-lambda/Dockerfile.custom-runtime#L10
The binary file without the flag is 14,737KB, with flag 12,279KB 👍

The first result is for 128MB:

Go runtime without tags flag:

Go custom runtime with flag:

Go custom runtime with flag ARM:

Almost the same for 256/512Mb. I don't see any improvements :(

Thanks for checking! I'm a little surprised that initialization seems to not make up the difference, but I suppose they probably have AL2 layers for the containers cached so the download isn't much different.
