Recently, we had a brown bag session presented by Rafi and Faisal (two of our software engineers) where they talked about caching mechanisms. They looked at the different ways of implementing caching in a web application. Using example code written in PHP they examined the benefits and drawbacks of the two most popular caching programs: Redis and MemCached. We are sharing their presentation here so that it can help you to know how to enhance application performance using caching. We regularly organize brown bag sessions on topics that will add value to your web application development. Please visit our SlideShare profile to see more of our presentations.
