Farewell to fsync(): 10× faster database tests with Docker
You’re writing an application that talks to a database—PostgreSQL, MySQL, MongoDB—and you need to write some tests. You want three things out of your tests: Realism: the closer your test setup is to production, the more likely you are to catch bugs with tests. Speed: Slow tests are expensive tests. Ease-of-use: You want running and writing tests to be easy, otherwise you’re less likely to do it. The problem is that interacting with a database is slow, so you want to avoid writing tes...

pquerna/ffjson: faster JSON serialization for Go
ffjson generates static MarshalJSON and UnmarshalJSON functions for structures in Go. The generated functions reduce the reliance upon runtime reflection to do serialization and are generally 2 to 3 times faster. In cases where ffjson doesn't understand a Type involved, it falls back to encoding/json, meaning it is a safe drop in replacement. By using ffjson your JSON serialization just gets faster with no additional code changes.

GitHub - stewartsmith/libeatmydata: libeatmydata (slowly migrating from launchpad)
An LD_PRELOAD library that disables all forms of writing data safely to disk. fsync() becomes a NO-OP, O_SYNC is removed etc.

The idea is to use in testing to get faster test runs where real durability is not required.

DO NOT use libeatmydata on software where you care about what it stores. It's called lib***EAT-MY-DATA*** for a reason.
