Performance Metrics

Performance metrics are fundamentally application specific and users of this library are encouraged to run their own tests to see if this library is a good fit. According to the data in this page, we can make the following generalities (based on the default compression rate and on relatively large files).
Relative to standard library in Go1.9:
- BZip2 decompression is about 1.3x to 1.6x faster
- DEFLATE decompression is about 1.6x to 2.3x faster
Relative to the canonical C implementations:
- Brotli decompression is about 0.3x to 0.5x as fast
- BZip2 compression is about 0.4x to 0.7x as fast
- BZip2 decompression is about 0.9x to 1.1x as fast
- DEFLATE decompression is about 0.6x to 0.7x as fast
As can be seen, we are still far from our goal of being within at least 80% of the C implementation in some cases. These will improve with further optimizations to this library and also with further improvements to the Go compiler itself.
Performance metrics are based on a system running the following:
| Hardware | Specification |
|---|---|
| OS | Linux Mint 17.1 Rebecca |
| CPU | Intel Core i7-3770 3.4 GHz |
| RAM | 6 GiB DDR3 1333MHz |
The software used are running the following versions:
| Software | Version |
|---|---|
| go | 1.9.2 |
| brotli | 1.0.2 |
| bzip2 | 1.0.6 |
| zlib | 1.2.8 |
| dsnet/compress | cc9eb1d7 |
The performance numbers below are generated by running the zbench.sh script. It runs benchmarks on multiple formats, multiple implementations of each format, on multiple test files, on multiple compression levels, and multiple file sizes.
The format of each trial is: <file_name>:<compression_level>:<file_size>
The different implementations tested are:
| Implementation | Description |
|---|---|
| std | The Go standard library implementation |
| ds | The implementation provided by this library |
| cgo | The canonical C implementation (see versions above) |
NOTE: Compressor not yet implemented.
