Chapter 2. Analyzing Julia Performance
Before we can try and optimize any Julia code we have written, we first need to understand its performance characteristics. Is the code fast enough for our needs? If not, how much slower is it from what it needs to be? And finally, can we understand where the bottlenecks are, so that we can prioritize where to focus our optimization effort? This chapter will show us the tools available in Julia to answer these questions and more. In later chapters, we will take a look at how to use this information to optimize our code.
In this chapter we will cover the following topics:
- Timing Julia functions
- Accurate benchmarking
- Profiling Julia functions
- Tracking detailed memory allocation
Timing Julia code
The first step to ...
