Fixing Performance & Memory problems and Contract Testing with Pact
Thursday 17th October 6:30pm at On the Beach offices, Aeroworks
This month we will have two talks for the price of one. Frederick Cheung will be giving us a preview of his upcoming RubyConf talk about identifying and fixing performance problems. and Elizabeth Dalton will be giving us a lightning talk on Contract testing your APIs with Pact.
Fixing Performance & Memory problems
Performance problems got you down? Do memory leaks strike fear in your heart?
In this session I'll share two real world stories of how you can solve performance problems and plug memory leaks. You'll learn how to use tools such as ruby-prof and stackprof, interpret their output and gain extra insight into how your code is performing.
When dealing with memory leaks, the biggest challenge can be finding them. You'll learn how to use rbtrace and ObjectSpace to identify what objects are being leaked and by which code, so that you can approach leaks with confidence.

Contract Testing with Pact
Contract testing is a strategy for testing API’s and clients in a micro-service architecture and Pact is a great tool to do this. This talk will explain the benefits of using contract testing over alternative methods such as integration testing.
