1 like•862 views
It seems that everywhere you look these days people are needing to work on high performance/low latency applications. If they're not already working on them, then they want to be. But what do you really need to know when you're working on performance-sensitive systems? Where do you get started? In this session, Trisha outlines things you need to consider when thinking about performance, covers some of the frequently-asked questions, and notes the pitfalls and common traps that developers fall into.
