Benchmark meaning gears 5 scattered11/18/2023 If you have many tasks, you can filter them by name using the search field on the bottom. You can use the checkboxes in the list inside the left panel to control which tasks get executed. If the benchmark prints anything on standard output or standard error during its run, that too will get included in the console area. Below it there is a console area that includes Attabench status messages. You can follow the benchmarking progress by looking at the status bar in the middle panel. The chart gets updated in real time as new measurements are made. Once you load a benchmark, you can press ⌘-R to start running benchmarks with the parameters displayed in We are going to look at how to define your own benchmark files later let's just play with the app first. It was used to generate the charts in the Optimizing Collections book. OptimizingCollections.attabench is an example of a real-life benchmark definition. It is a useful starting point for starting your own benchmarks. SampleBenchmark.attabench is a simple example benchmark with just three tasks. The repository contains two examples, so you don't need to start from sratch: Each benchmark contains executable code for one or more individually measurable tasks that can take some variable input. When the app starts up, it prompts you to open a benchmark document. You may create many result documents for any benchmark. Results documents remember which benchmark they came from, so you can stop Attabench and restart any particular benchmark run at any point. attabench), and a results document containing benchmark timings (extension. Installationįollow these steps to compile Attabench on your own:Īttabench has two document formats: a benchmark document defining what to test (with the extension. It contains a lot of benchmarks made with Attabench I'm positive you'll find it entertaining and informative. ![]() If you find Attabench useful in your own project, please consider buying a copy of my book! It produces are chock full of strange and wonderful little mysteries. But it's shockingly fun to play with, and the graphs What polite people might call a little messy. (It has to be noted though that this opinion has been somewhat weakened during the implementation process.)Īttabench was made in a hurry for a single use case, so its code is At the time, it seemed easier to build a custom chart renderer from scratch using Core Graphics than to mess with a bunch of CSV files and pivot tables in Excel. Attabench's default log-log plots are ideal for seeing your algorithm's performance at a glance.Īttabench was originally created to supply nice log-log charts for my dotSwift 2017 talk and Optimizing Collections book. It works by repeatedly performing the same operation on random data of various sizes, while continuously charting the results in nice plots. This app is for microbenchmarking low-level algorithms with one degree of freedom (usually size). Internal Details: The Attabench Protocol.That package provides a portable benchmarking solution that works on all platforms that Swift supports, and it is being maintained by the Swift Standard Library team.Īttabench is a microbenchmarking app for macOS, designed to measureĪnd visualize the performance of Swift code. ![]() ![]() This package has been largely superseded by the Swift Collections Benchmark package.
