“ What is the fastest programming language ”, To answer this question ,The Benchmarks Game Specially designed performance test for mainstream programming languages . The test items include （ You can click the end of the text to read the original text to view the details ）：

• fannkuch-redux
• n-body
• spectral-norm
• mandelbrot
• pidigits
• regex-redux
• fasta
• k-nucleotide
• reverse-complement
• binary-trees

According to The Benchmarks Game A visual chart is made of the test data of , As shown below , Grey reflects time efficiency , Shorter means better performance , Brown is a weighted value based on execution time and memory overhead .

You can see , Some of the results were somewhat unexpected , such as Python, Although it is well known that its performance is relatively backward , But I didn't expect to be the bottom in terms of execution time .C、C++ and Rust The execution time of shows a leading edge , The following ones include C# and Julia,Go and Java Performance is quite , But it's more behind .

And then there will be Node.js、Swift and Dart, as well as PHP, These languages also present different performance gaps .
