I don't know of any cross-library comparison benchmark. Also, if a library does ship with an internal benchmark, it usually uses a different number of data/parity shards and different shard size, compared to other library benchmarks, which makes comparison difficult. I wrote an MIT-licensed ReedSolomon module for Node [1], with native C++ multi-core throughput. The internal benchmark (node benchmark.js) provides latency and throughput measurements for data=10, parity=4 for a variety of shard sizes, and the number of data/parity shards can be adjusted for comparison. It's not yet using optimized assembler or SIMD like Klaus Post's implementation, but it is compatible and also based on Backblaze's implementation, as well as including a pure Javascript implementation for browser use.
