# Remaining Benchmark Game languages compared with Mech

Time × Mech uses the fresh unchanged fastest Mech AOT control from the same cohort for both profiles. Fastest LOC × Mech compares fastest sources; smallest LOC × Mech compares smallest sources. Below 1× means faster or shorter than Mech.

Full prescribed workloads; medians of three fresh processes. All times are seconds. Complete application helpers/FFI count toward LOC; general library implementations are excluded.

## Excluded full-workload failures

- regexredux:regexredux-ada-pcre2: Command '['/Users/cim310/.codex/worktrees/clbg-nbody-v04/mech/benchmarks/clbg/remaining-languages-comparison/20261011/support/ada-pascal/builds/regexredux-ada-pcre2/regexredux-ada-pcre2']' returned non-zero exit status 1.; 
raised STORAGE_ERROR : stack overflow


## Separately measured corrections

- regexredux:regexredux-ada-pcre2-heap: Use standard GNAT Unbounded.Aux heap storage and borrowed string views instead of full-input To_String copies and stack-sized replacement buffers. Keep every count, PCRE2 call and ordered replacement; include the application allocation callback and all bindings in LOC. Three fresh full-size samples and a fresh unchanged Mech control; the failed original is retained above.
