Performance — gjson-style fast-skip
Ported gjson's >'\\' single-comparison fast-skip to three hot loops. The trick skips all non-structural bytes (those > 0x5C) in one unsigned comparison per byte, reducing branch overhead.
| Payload | Before | After | Change |
|---|---|---|---|
| Small (190B) | 382 ns | 339 ns | -11.3% |
| Medium (2.4kB) | 3,899 ns | 3,141 ns | -19.4% |
| Large (24kB) | 20,788 ns | 20,114 ns | -3.2% |
Now benchmarks against gjson and sonic
Added tidwall/gjson (15.5k⭐) and bytedance/sonic (9.6k⭐) to the benchmark suite.
Large payload — the definitive ranking:
| Library | time/op | allocs |
|---|---|---|
| jsonparser | 20,114 ns | 0 |
| gjson | 22,756 ns | 2 |
| easyjson | 33,771 ns | 134 |
| sonic | 41,053 ns | 71 |
| ffjson | 59,063 ns | 144 |
| encoding/json | 130,565 ns | 147 |
jsonparser is the fastest across ALL payload sizes and the only zero-allocation parser.
