The state of server-side Swift
This document provides an overview of server-side Swift. It discusses the history and evolution of Swift, why Swift makes sense for server-side development due to its performance and memory efficiency. It also summarizes the current Swift web server toolkits available, including Perfect, Vapor and Kitura, and provides benchmarks comparing the performance of Perfect to other frameworks.

Up until now over 250 proposals have been accepted and implemented in the Swift language and toolchain and over 23,000 pull requests to make the Foundation framework available on Linux. It also runs down the other scale on Raspberry Pi and considerable efforts are being made to make Swift available for Android as well.

From all of the toolkits available we went with Perfect because it fared the best out of the available frameworks at this moment. To test how well it is doing we used two DigitalOcean VM instances located in Amsterdam.
