Our workloads are a bit different and obviously our machines are a bit different.
Mine only compares mattn/go-sqlite3 to my own fork of https://github.com/bvinc/go-sqlite-lite. go-sqlite-lite seemed like an easier-to-use version of crawshaw's package but it was abandoned so I forked it to bring it up to date.
I agree, for best performance you shouldn't use mattn/go-sqlite3. It does some extra work in hotpaths. It is also higher level and easier to use though. So pick what's important to you.
