Semgrep Cuts Taint Analysis Time 75% Using OCaml 5.0 Multicore
June 18, 2026
Semgrep rewrote interfile taint tracking as a single-pass multicore workload using OCaml 5.0, achieving up to 75% faster static analysis on large codebases. This is a concrete performance win for teams running Semgrep in CI pipelines with significant interfile dependency graphs.
