Scheme Benchmarks
Based on the Larceny benchmarks . Code on GitHub
Completed full run: Chez, Hawk, Loko, GambitC, Bigloo, Stalin, Guile, MIT, S7, Larceny, Chicken, Racket. Run on AMD Ryzen 9 5900X 12-Core Processor in Arch Linux Docker, serially, with a 6 GiB container memory limit and two CPUs. One repetition; 300-second CPU limit. CSV data ; package versions ; machine details ; snapshot status .

SAFE vs. UNSAFE optimizations Stalin requires -On because integer overflow checking is not implemented by that compiler.
The benchmark results on this page are collected in safe mode. This means various optimisations are turned off for each implementation. If you need code to run as fast as possible, look into that, the Readme on GitHub contains a few pointers for the different implementations.
Feel free to run the benchmarks yourself without safety turned on. You'll probably need to modify the bench file for that.
Actual R7RS Support
Many of these implementations do not fully implement R7RS, but instead there is a bit of "shim" code. You can find this by looking at src/<Name>-prelude.scm and src/<Name>-postlude.scm, to see which changes are necessary. Some changes are also made by the bench script, especially relating to imports.
However, all of these implementations are "close enough" to R7RS to run a non-trivial amount of code.
Run status All published implementations have completed their benchmark attempts. Failures and timeouts are retained in the CSV and shown in the results.
S7 emitted no result records for pi, dynamic, chudnovsky. These cells show the missing-result icon.
Hawk 0.12 update: All 57 Hawk benchmarks were rerun serially in Docker using Hawk 0.12 (tag v0.12, commit 5ccf66a4587f) (RelWithDebInfo). One repetition; 300-second CPU limit. Other implementations retain their existing measurements, including the previous mbrotZ rerun for Chez, GambitC, S7, Larceny, and Racket. Full provenance is recorded in status.json.
Test ranks (1-9) The following list shows how often a given Scheme was in the top 9. Every 1 means that this Scheme was first place, every 2 means second place, etc. Sorting is done in ascending order by summing the places (10 for every missing number).
