Check memory usage when emulating x86 images on M1/M2 macs #102

Open webmaster128 opened 1 year ago

When cross compiling the 0.12.10 x86 image on ARM64 macs, the RUSTFLAGS='-C link-arg=-s' cargo build --release step in the builder image required a lot of RAM. 20 GB was not enought but 25 GB worked.

For maintaining this repository this is fine. However, I wonder what the users of rust-optimizer/workspace-optimizer have to configure when using the resulting image. We need to measure this (test a few settings with a few contracts) and document it.

It is likely the memory consumtion of the Rust compiler changed between 0.12.10 (Rust 1.65.0) and 0.12.9 (Rust 1.64.0).

A user with an M1 machine (probably 8 core, 16 GB M1 mac) and those settings cannot cross-compile contracts with 0.12.10.
