+# Ktor with async postgres Benchmarking Test
+
+## Important Libraries
+This sets up testing using [Ktor](https://ktor.io/), with a couple of async PostgreSQL clients:
+* [jasync-sql](https://github.com/jasync-sql/jasync-sql) A pure Kotlin MySQl/PostgreSQL client, with coroutines integration
+* [reactive-pg-client](https://reactiverse.io/reactive-pg-client/guide/java/) A mature async PostgreSQL client with pipelining and batch support
