--- title: 'New screencast: Improving Performance for Real-time Requests' teaser: tags: news,web,performance,rails,upcase author: Chad Pytel published_on: 2013-05-09 --- We're pleased to announce our newest screencast video on Upcase, [Improving Performance for Real-time Requests](https://thoughtbot.com/upcase/improving-performance?utm_source=giantrobots&utm_medium=blog&utm_campaign=performance). This video, with thoughtbot CTO Joe Ferris, shows you how to tune performance using a real world example. Starting with an action that takes 3 seconds to respond and performs over 1600 database queries, Joe is able to reduce response time to 300ms and drop database usage to just 5 queries. This video specifically focuses on what Joe calls "real-time requests". That is, requests that must return all of their data to the user in the request-response cycle, without relying on background jobs or persistent caching. _[Upcase](https://thoughtbot.com/upcase/join?utm_source=giantrobots&utm_medium=blog&utm_campaign=performance) subscribers get this new video included with their monthly subscription._ Slow Rails applications annoy users and lead to lost revenue.
