Hi, I think this issue is related to what happened in terms of optimizations in go 1.18.3_1: --- Add amd64 microarchitecture level knobs for the Go compiler. Note that this will affect only the compiler itself, port users will still need to set GOAMD64 in the environment to adjust the microarchitecture of the compiled code --- I've found this optimizations interesting, e.g.: --- The current high level steps to reduce binary size are:
1. Use Rust 1.32.0 or newer (which doesn't include jemalloc by default) 2. Add the following to Cargo.toml <https://doc.rust-lang.org/cargo/reference/manifest.html>: [profile.release] opt-level = 'z' # Optimize for size. lto = true # Enable Link Time Optimization codegen-units = 1 # Reduce number of codegen units to increase optimizations. panic = 'abort' # Abort on panic strip = true # Strip symbols from binary* *strip = true requires Rust 1.59+. On older Rust versions, run strip manually on the resulting binary. --- I was searching for cargo stripping instead of using STRIP_CMD and I found this but this means that we have to hack ports Cargo.toml's or should be upstream to implement a [profile.release]?
