## **Load Time Benchmark**
## Result
Metric | main (node-sql-parser) | replace-with-sqlparser-rs (sqlparser-ts)
-- | -- | --
Avg Page Load | 459.6ms | 463.9ms
Median Page Load | 446.3ms | 450.2ms
Min | 382.0ms | 359.1ms
Max | 549.0ms | 643.2ms
Avg DOM Content Loaded | 456.4ms | 460.3ms
Individual Values | 549, 439, 382, 390, 433, 438, 453, 519, 469, 524 | 443,
452, 368, 359, 406, 449, 480, 574, 643, 467
No measurable performance difference. Both branches are within noise margin
(~4ms difference in median)
