## What it is
A benchmark suite comparing the performance of serialization libraries on the JVM, such as protobuf, thrift, avro, and Java built-in serialization. It provides reproducible test code and published results via its wiki.

## Use cases
- compare JVM serialization library performance
- choose a serialization format for a Java service
- benchmark protobuf vs avro vs kryo
- measure serialization throughput and latency on the JVM
- evaluate serialization library tradeoffs before adoption

## When to choose
- you need up-to-date comparative data on JVM serializers
- you want to run your own serialization benchmarks on the JVM

## When to avoid
- you need a serialization library itself rather than a benchmark
- you target non-JVM platforms
- you need a maintained library with a license for production use

## Facets
- artifact type: dataset
- maturity: maintenance
- function: benchmarking, serialization, developer-tools
- domain: performance, developer-tools
- platform: jvm, cross-platform
- tags: serialization-benchmark, java, microbenchmark, jvm
