Benchmark Results

Platform: linux x64 | Runtime: Bun 1.4.3 | Date: 2026-10-13

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	295.0 µs	1.38 ms	🟢 4.7x
Medium typed initializers	1318 KiB	498.9 µs	5.08 ms	🟢 10.2x
Large typed initializers	5321 KiB	848.3 µs	19.50 ms	🟢 23.0x

In-Process API — Cached

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

oxc-transform	11.2 µs (7.7x)	34.6 µs (41.4x)	118.8 µs (131.7x)	765.7 µs (342.1x)	513.8 µs (136.0x)	1.42 ms (229.7x)
TypeScript 7 (CLI)	55.13 ms (37887.4x)	56.90 ms (68099.0x)	58.50 ms (64861.1x)	74.53 ms (33300.8x)	69.29 ms (18338.1x)	86.04 ms (13948.0x)

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	6.5 µs (3.8x)	9.8 µs (6.4x)	41.4 µs (48.1x)	290.3 µs (94.5x)	293.9 µs (75.7x)	652.8 µs (104.3x)
oxc-transform	11.2 µs (6.5x)	34.6 µs (22.4x)	118.8 µs (138.0x)	765.7 µs (249.3x)	513.8 µs (132.4x)	1.42 ms (226.4x)
dtsx (no-cache)	1.7 µs	1.5 µs	861 ns	3.1 µs	3.9 µs	6.3 µs
TypeScript 7 (CLI)	55.13 ms (31980.0x)	56.90 ms (36846.3x)	58.50 ms (67971.8x)	74.53 ms (24263.5x)	69.29 ms (17861.3x)	86.04 ms (13750.7x)

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	4.44 ms (65.1x)	8.88 ms (25.5x)
dtsx	68.2 µs	347.9 µs
oxc-transform	12.18 ms (178.6x)	25.64 ms (73.7x)
tsc	310.40 ms (4552.1x)	611.51 ms (1757.9x)
