Benchmark Results

Platform: linux x64 | Runtime: Bun 1.4.0 | Date: 2026-08-26

isolatedDeclarations vs Semantic Generation

Uncached end-to-end declaration generation over identical, fully annotated sources.

Workload	Input	isolatedDeclarations	Semantic	Speedup
Small typed initializers	256 KiB	314.7 µs	1.49 ms	🟢 4.7x
Medium typed initializers	1318 KiB	626.4 µs	5.62 ms	🟢 9.0x
Large typed initializers	5321 KiB	790.6 µs	21.42 ms	🟢 27.1x

In-Process API — Cached

Smart caching (hash check + cache hit) for watch mode, incremental builds, and CI.

In-Process API — No Cache

Raw single-transform comparison (cache cleared every iteration).

Tool	Small (~50 lines)	Medium (~100 lines)	Large (~330 lines)	XLarge (~1050 lines)	XXLarge (~2000 lines)	Huge (~5000 lines)
zig-dtsx	7.5 µs (3.6x)	11.7 µs (6.7x)	47.2 µs (43.3x)	268.4 µs (82.0x)	329.8 µs (76.0x)	752.6 µs (69.0x)
oxc-transform	11.5 µs (5.4x)	38.8 µs (22.1x)	136.3 µs (125.1x)	831.0 µs (253.8x)	665.6 µs (153.3x)	1.68 ms (153.7x)
dtsx (no-cache)	2.1 µs	1.8 µs	1.1 µs	3.3 µs	4.3 µs	10.9 µs
TypeScript 7 (CLI)	68.48 ms (32509.6x)	67.26 ms (38403.8x)	68.55 ms (62912.7x)	83.76 ms (25580.9x)	76.42 ms (17601.4x)	92.85 ms (8514.5x)

Note: TypeScript 7 is CLI-only. Each measurement includes ~40ms process spawn overhead, so it is not directly comparable to the in-process tools above. It is reported separately from the in-process tools.

Multi-File Project

All tools processing files in-process sequentially.

Tool	50 files	100 files
zig-dtsx	4.38 ms (54.7x)	9.14 ms (23.6x)
dtsx	80.0 µs	386.7 µs
oxc-transform	13.63 ms (170.4x)	27.94 ms (72.3x)
tsc	334.83 ms (4186.8x)	649.32 ms (1679.0x)
