Performance

I have benchmarked Crystal-Redis against several other client libraries in various programming languages in this blog article.

Here are some results:

  • Crystal: With this library I get > 680,000 commands per second using pipeline on a MacBook Air with a single client thread.

  • C: The equivalent program written in C with Hiredis gets me 340,000 commands per second.

  • Ruby: Ruby 2.2.1 with the redis-rb and Hiredis driver handles 150,000 commands per second.

Read more results for Go, Java, Node.js.

Status

I have exercised every API method in the spec and built some example programs. There is no production use yet.

I took great care to make this library very usable with respect to API, reliability and documentation.
