According to the competition benchmarks (https://github.com/nikita-volkov/bytestring-builders-benchmark), this library provides on average the fastest builder of strict bytestrings. Practical benchmarks have proven it to be highly performant as well. The encoders from the "postgresql-binary" library have shown a stable performance improvement by factors of up to 10 after the migration from the standard builder to "bytestring-strict-builder".
