Benchmarks

In terms of benchmarks, the following metrics can be used to evaluate a serialization/deserialization process:

1. Speed - how fast is the serialization/deserialization process is compared to other serializers/deserializers
2. Size - how much space is needed to store the serialized data (in particular for a schema-less serializer, like FlatMessage, the size needed to store the metadata is relevant)

Additionally, the for FlatMessage another relevant metrics are:

1. Safe vs Unsafe deserialization (and their performance implications)
2. Zero-copy deserialization (and its performance implications)
3. FlatMessageStruct vs FlatMessagePacked for nested structures (and their performance implications in terms of speed and size)
