SQLite/HTTP Server Performance Benchmark

This benchmark provides a overview of the different SQLite driver performances available in Go. For benchmarking a simple HTTP server is used to perform random read queries on the database.

For benchmarking the hey load generator is used to call the HTTP server (with 50 concurrent requests).

Driver Overview

Implementation

The implementation consists of a simple HTTP server that runs a single select query on the SQLite database for each request.

SELECT * FROM foo WHERE rowid = ? -- where ? is a random number between 1 and 10000

The SQLite database has the following schema and contains 100000 rows with random values.

CREATE TABLE foo (id integer, value integer);

See any of the subfolder/main.go files for more details.

Benchmark

The benchmark was run on a MacBook Pro 2020 with a 2.3 GHz Quad-Core Intel Core i7 and 32 GB of RAM.

The server is started with a configurable number of "connections" to the SQLite database, here called poolsize. Once the server is running hey is used to run the HTTP load test. See runbenchmark.go for details.

All reports of hey can be found in the result_*.txt files.

Observations

• The performance results between the packages do not differ that much.
• Limiting the number of connections/poolsize to the SQLite database to roughly the number of CPU cores on the machine gives best performance results.
