The goal of these benchmarks is to provide thorough and complete benchmarks for various rust serialization frameworks.
These benchmarks are still being developed and pull requests to improve benchmarks are welcome.
Calculate the number of messages per second that can be sent/received with various rust serialization frameworks and compression libraries. Documentation
All tests benchmark the following properties (time or size):
- Serialize: serialize data into a buffer
- Deserialize: deserializes a buffer into a normal rust object
- Size: the size of the buffer when serialized
- Zlib: the size of the buffer after zlib compression
Zero-copy deserialization libraries have an additional set of benchmarks:
- Access: accesses a buffer as structured data
- Read: runs through a buffer and reads fields out of it
- Update: updates a buffer as structured data
Some benchmark results may be italicized and followed by an asterisk. Mouse over these for more details on what situation was benchmarked. Other footnotes are located at the bottom.
This data set is composed of HTTP request logs that are small and contain many strings.
For operations, time per iteration; for size, bytes. Lower is better.
