We are in the era of Big Data, security challenges, complex problems, and large-scale services. Unfortunately, software engineers and architects often deprioritize their products' efficiency aspects for various reasons. This often results in overpaying millions of dollars on infrastructure bills, failed projects, or overpriced vendors. In this talk, Bartek, an engineer and software architect at Red Hat, and author of the "Efficient Go" book will help you conquer those performance problems! You will learn the pragmatic process of optimizing your systems on multiple levels using simple frameworks and open-source observability tools. It might be easier than you think!        What you'll learn: * How to optimize software in a pragmatic way * When to optimize on the system level (switch projects, vendors or scale out) vs on the algorithm or code level * How to set clear performance goals * How to use observability to measure and find efficiency bottlenecks.
