TypeBox 1 Compile is significantly slower than TypeBox 0.34
review
TypeBox 1 Compile is 10x slower and use significantly more memory than TypeBox 0.34 compile.
TypeBox 0.34 using `TypeCompiler.Compile`
```ts
import { Type } from '@sinclair/typebox'
import { TypeCompiler } from '@sinclair/typebox/compiler'
const schema = Type.String()
const stacks = <any[]>[]
const t1 = performance.now()
const m1 = process.memoryUsage().heapUsed
for (let i = 0; i <= 100_000; i++) stacks.push(TypeCompiler.Compile(schema))
const m2 = process.memoryUsage().heapUsed
const t2 = performance.now()
console.log('Time:', t2 - t1, 'ms')
console.log('Memory:', (m2 - m1) / 1024 / 1024, 'MB')
```
TypeBox 1 using either `typebox/schema` or `typebox/compile`
```ts
import { Type } from 'typebox'
import { Compile } from 'typebox/schema'
const schema = Type.String()
const stacks = <any[]>[]
const t1 = performance.now()
const m1 = process.memoryUsage().heapUsed
for (let i = 0; i <= 100_000; i++) stacks.push(Compile(schema))
const m2 = process.memoryUsage().heapUsed
const t2 = performance.now()
console.log('Time:', t2 - t1, 'ms')
console.log('Memory:', (m2 - m1) / 1024 / 1024, 'MB')
```
This would produce the result as follows
| Method | Time | Memory |
| --- | --- | --- |
| TypeBox 0.34 | 228 ms | 108 MB |
| TypeBox 1 `typebox/schema` | 2259 ms | 226 MB |
| TypeBox 1 `typebox/compile` | 2232 ms | 230 MB |
TypeBox 1 compile is slower than TypeBox 0.34 by 10x and consumes more memory usage by 2x
This happens in both Node and Bun
- Bun: 1.3.11
- Node: 24.14.0
Benchmark on M1 Max 64GB
- `Darwin 25.3.0 arm64 arm`
TypeBox version:
- `@sinclair/typebox` - 0.34.49
- `typebox` - 1.1.16
Additional note:
- This is reproducible on a newly created project
- This happens starting from TypeBox 1.0.0
