Compressor Benchmark Tool

compbench is a simple tool that runs some compression benchmarks and prints them in CSV format.

Currently, the tool supports zstd, lz4, and iguana.

Usage

Just go install and invoke the tool. The silesia test corpus is embedded into the tool.

$ go install github.com/SnellerInc/compbench@latest
$ compbench

If you do not have the requisite binaries installed (zstd, lz4, etc.), then the tool will skip running benchmarks for those algorithms.

You can use -f=filename to override the internal test corpus with a file from the local filesystem. The tool reads the entire test corpus file into memory, so it should be smaller than the available memory, and large enough to effectively amortize the overhead of exec-ing the compressor and decompressor sub-processes. Files on the order of tens to hundreds of megabytes work well.
