Benchmarking mattn/go-sqlite3 vs modernc.org/sqlite vs cvilsmeier/sqinn-go

SQLite: CGO vs no CGO

This repo benchmarks mattn/go-sqlite3 against modernc.org/sqlite which is a translation of SQLite3 from C to Go. This translation allows the latter package to avoid CGO since there is no C.

My initial observations showed it being twice as slow as mattn/go-sqlite3 and this repo is to test that observation.

See the blog post for details.

Fork

This fork differs from the original in the following aspects:

• After querying database rows, iterate over it (scan them). Why? Because without iterating, values might not be fetched from the database.

• Add benchmark for https://github.com/cvilsmeier/sqinn-go

Machine Specs

• OS: x86_64 GNU/Linux (Debian 11.5)
• RAM: 16 GB
• Disk: 1TB NVME SSD
• Processor: 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz

Summary

For small database workloads, the library you're using does not matter so much. For medium to large database workloads however, you'll be better off with cvilsmeier/sqinn-go.
