# BigNumber Benchmarks The benchmark scripts measure extremely large number operations and script number serialization performance. All results below were gathered on Node.js v22.16.0 using the `dist` build of the SDK. Each benchmark was executed with 200,000-digit inputs to stress the implementation. ## Addition and Multiplication Command: ```bash node benchmarks/bignumber-bench.js 200000 1 1 ``` | Branch | mul large numbers | add large numbers | | --- | --- | --- | | master (pre-May-2025) | 6364.11ms | 13.04ms | | fix-mem (May-2025) | 13.60ms | 2.64ms | ## Serialization Command: ```bash node benchmarks/serialization-bench.js 200000 1 ``` | Branch | toSm big | toSm little | fromSm big | fromSm little | fromScriptNum | | --- | --- | --- | --- | --- | --- | | master (pre-May-2025) | 6.12ms | 10.11ms | 6.35ms | 12.56ms | 3.39ms | | fix-mem (May-2025) | 8.46ms | 8.12ms | 27.77ms | 11.16ms | 10.31ms | ## Transaction Verification Command: ```bash node benchmarks/transaction-bench.js ``` | Branch | deep chain verify | wide transaction verify | large tx verify | nested inputs verify | | --- | --- | --- | --- | --- | | fix-mem (May-2025) | 3335.76ms | 2930.86ms | 1534.36ms | 1198.08ms | ## SymmetricKey Encryption/Decryption Command: ```bash node benchmarks/symmetric-key-bench.js ``` | Branch | encrypt large 2MB | decrypt large 2MB | encrypt 50 small | decrypt 50 small | encrypt 200 medium | decrypt 200 medium | | --- | --- | --- | --- | --- | --- | --- | | fix-mem baseline | 8609.78ms | 8372.23ms | 34.02ms | 48.58ms | 859.38ms | 960.16ms | | optimized AESGCM (round 1) | 7678.65ms | 7619.82ms | 60.23ms | 35.21ms | 871.89ms | 763.13ms | | optimized AESGCM (round 2) | 2026.89ms | 1793.35ms | 15.01ms | 7.88ms | 213.35ms | 169.37ms | ## Reader/Writer Operations Command: ```bash node benchmarks/reader-writer-bench.js ``` | Branch | mixed ops | large payloads | 3000 small payloads | 400 medium payloads | | --- | --- | --- | --- | --- | | fix-mem baseline | 9.93ms | 127.49ms | 27.86ms | 41.71ms | | optimized utils.ts | 5.02ms | 91.93ms | 19.04ms | 53.80ms |
