PerfChecker.jl — Installation & First Performance Checks| Tutorial 1

Get started with PerfChecker.jl: install the VS Code extension, prepare your Julia environment, and compare performance across package versions. In this first tutorial, we measure a small Bibliography.jl export with BenchmarkTools, inspect the results, then discover and measure an existing TestItem directly in VS Code. You’ll learn how to: • Set up the extension and a dedicated controller project. • Separate preparation from the operation being measured. • Compare two released versions and interpret timings and allocations. • Save and reopen collected observations. • Measure existing TestItems and read their correctness and performance status.
