We extended our performance monitoring solution to PHP and Serverless, with plans for Ruby and Java + Springboot support soon. A new view in Performance, Trends, shows improved and regressed transactions in relation to releases. We used Trends to investigate a potential performance regression after shipping a new feature, Web Vitals, which showed a dramatic increase in duration for a specific query. The root cause was found to be a bug in our Snuba search infrastructure that was causing the Abstract Syntax Tree to be processed multiple times, and we fixed this by implementing a cache to store translated nodes. This demonstrates the value of using performance monitoring tools like Trends to communicate with your code and identify areas for improvement.
