Rust's built-in benchmark tests are a simple starting point, but they use unstable features and therefore only work on Nightly Rust.
Criterion is a more sophisticated alternative.
Hyperfine is an excellent general-purpose benchmarking tool.
Custom benchmarking harnesses are also possible..
Benchmarks are built with the --test option to rustc which creates a special executable by linking your code with libtest.
The executable automatically runs all functions annotated with the #[bench] attribute.
Cargo passes the --bench flag to the test harness to tell it to run only benchmarks..
Benchmarking is a powerful way to assess the strengths and weaknesses of your business and understand what makes your competition so tough.
By comparing your business to others, you can set realistic goals and find new and efficient methods for achieving them..
Rust comes with built-in support for benchmarking, which is part of the standard library's test module.
To create a benchmark test, you need to add a bench function in the test module and annotate it with #[bench] .Mar 25, 2023.
Benchmarks allow you to determine how well your game is performing compared to similar titles on the app store, without requiring any changes to your code.
This knowledge can help you make decisions and focus your development on improving game metrics and making a better game..
The definition of benchmarking in business: Business benchmarking is the process of comparing industry and general business best practices against your own to identify performance gaps and achieve competitive advantages.
This can be applied to any product, process, function, or approach in business..
In Rust, benchmarking is the process of measuring the performance of Rust code.
This can be done to compare the performance of different versions of the same code, or to compare Rust code to the code written in other languages..

Many companies use benchmarking to improve the quality of their products.
This often involves studying their competitors' products to determine how they outperform similar goods.
This can result in improvements to a company's products, which will ultimately affect customer satisfaction and their bottom line..
Don’t force a narrative
A lot of new developers are starting to use Rust and they have not been exposed to benchmarking before.
Just because Rust is fast and memory-efficient doesn’t mean that your code will be fast as well.
The features that make Rust what it is, comes with a great cost if we don’t know how to properly use them.
Probably, if you search how to benchmark in Rust the first result that you'll get is "Criterion".
Recently Rust published a roadmap for 2024 where they mentioned the possibility to adopt Criterion officially.
It's worth mentioning that Rust comes with a benchmarking feature but is currently unstable as it says in Rust documentation.
Creating a benchmark and reports mean nothing if they are ephemeral, as no one else can reproduce what you did including yourself when your memory fades.
1) Include instructions in the readme on how to run the benchmark and generate any necessary output (eg:.
1) Commit the benchmark data to the repo.
This may be a little controversial due to benchma.
Criterion does a great job comparing performance of implementations, but we have to rely on profiling tools to show us why one is faster than the other.
We’ll be using the venerable valgrind, which doesn’t have a great cross platform story, so I’ll be sticking to linux for this.
And we can navigate in kcachegrind to lines of code with the most inst.
If there is one thing to takeaway from this post: benchmark with Criterion.
Never written a Rust benchmark? Use Criterion.
Only written benchmarks against Rust’s built in bench harness.
Switch to Criterion:.
1) Benchmark on stable Rust (I personally have eschewed nightly Rust for the last few months!).
2) Reports statistically significant changes bet.
