At Discourse, we have been eager to adopt YJIT ever since Shopify’s Ruby & Rails Infrastructure team declared it production-ready. After witnessing promising local benchmarks, we began running our production Rails applications with Ruby 3.2’s YJIT enabled on selected clusters in early May 2023. We then spent some time measuring its real-world performance. We are excited to share the positive results we observed. Based on these findings, we have now enabled YJIT across all of our hosting, and self-hosters can opt-in to do the same.
