benchmarking

Path: examples/benchmarking.

A small control mod whose #[cfg(test)] module is a suite of #[factorio_rs::bench] functions, lowered Rust (map/filter/collect), parity % experiments, and raw lua! append idioms.

Try it

cd examples/benchmarking
factorio-rs bench                         # all benches (default --profile release)
factorio-rs bench pre_allocate            # name filter (substring)

Example report:

running 2 benches
bench benches::no_pre_allocate ... time: [9.490 ms 9.967 ms 16.872 ms] ±0.383 ms
bench benches::pre_allocate    ... time: [9.489 ms 9.951 ms 16.487 ms] ±0.474 ms

Requires a Factorio binary (FACTORIO_PATH). Details: Benchmarking.

What’s inside

Bench	What it times
no_pre_allocate	fill a fresh Lua table 1..100000
pre_allocate	same loop after a sparse x[1024] = nil pre-size
