Gotoken bench example

bench is a simple benchmarking tool for profiling gotoken.

Requirements

This example app expects a 1GB test file that is not checked in to the repository. To download it, use the testdata/get_wiki_1gb.py script.

Usage

The benchmark is a CLI app. By default, all encodings are benchmarked in single-threaded and multi-threaded mode. To limit the benchmark to a specific encoding or number of threads, use the -encoding or -threads parameters, like this:

• ./bench -encoding r50k_base
• ./bench -threads 1
• ./bench -encoding cl100k_base -threads 16

Additionally, the -pprof flag can be used to write out CPU profiling data. This will be saved to ./bench.pprof, and can be accessed by running:

• go tool pprof -http :8080 bench bench.pprof
