A fast Rust statusline renderer for Claude Code: a byte-parity rewrite of the TypeScript project phosphorflux, with a full-screen terminal TUI built with ratatui. Its warm render median is 6.8 ms versus 247.8 ms for the TypeScript version on the same Intel machine (~36x), and 8.4 ms versus 478.5 ms on an M2 (~57x).
| Implementation | Intel median | Intel p10–p90 | CPU @1s (Intel) | M2 median | M2 p10–p90 | CPU @1s (M2) | Speedup vs TS (Intel / M2) |
|---|---|---|---|---|---|---|---|
| TypeScript (phosphorflux) | 247.8 ms | 241.0–253.2 ms | ~24.8% | 478.5 ms | 374.5–510.3 ms | ~47.8% | 1x |
| Bash (coralline) | 43.4 ms | 42.5–44.3 ms | ~4.3% | 44.6 ms | 43.5–47.1 ms | ~4.5% | ~5.7x / ~10.7x |
| Rust (phosphorpulse) | 6.8 ms | 6.4–7.7 ms | ~0.7% | 8.4 ms | 7.7–8.9 ms | ~0.8% | ~36x / ~57x |
Single render including process startup. Both machines: median of 30 timed runs after 5 warmups; on each machine all three implementations were fed the same input JSON (Intel measured 2026-08-16). The two machines used different environments and input JSON, so absolute values are not comparable across machines — compare the ratios instead. All Bash rows run the same coralline statusline.sh. Local measurements, not a committed benchmark.
