Owner

Refs #53.

Background

#56 added CARGO_BUILD_JOBS=1 + CODEGEN_UNITS=256 and the amd64 build went from 1m11s to 2m7s before OOMing again. Same SIGKILL signature, same unrecoverable Forgejo logs.

Fix

Drop release opt-level from 3 to 2. portal-relay is an I/O-bound network relay; the runtime difference between -O2 and -O3 is in the noise for the workload, and the rustc memory difference is measurable. -O2 is what most distros ship for serverside Rust binaries.

Validation

cargo fmt --check clean
cargo test --locked 86 passed, 3 ignored
cargo clippy --locked --all-targets -- -D warnings clean

Will validate the actual amd64 image build with another v0.0.0-debug-amd64-2 tag after merge.

PR #56 added `CARGO_BUILD_JOBS=1` and `CODEGEN_UNITS=256`. The amd64
Kaniko build then ran further (1m11s -> 2m7s) but still OOMed during
rustc, with logs once again unrecoverable through the Forgejo Actions
API.

Drop release opt-level from 3 to 2. portal-relay is an I/O-bound
network relay where the runtime difference between -O2 and -O3 is in
the noise; the rustc memory difference is measurable and lets the
build fit on the amd64 runner without depending on swap.

LTO is still off (default), debug info is still stripped, and other
release-profile defaults are unchanged.
