Benchmarks

The benchmarking is conducted against CGo implementation of SQLite driver (https://github.com/mattn/go-sqlite3).

Benchmark tests are inspired by and closely repeat those described in https://www.sqlite.org/speed.html.

Doing benchmarks

Benchmarks are run by custom runner and invoked with

go test -v .

Additional command line arguments:

flag	type	default	description
-mem	bool	false	if true: benchmarks will use in-memory SQLite instance, otherwise: on-disk instance
-rep	uint	1	run each benchmark multiple times and average the results. this may provide more stable results
