简介:2017年的golang、python、php、c++、c、java、Nodejs性能对比 续集更新 本人在PHP/C++/Go/Py时,突发奇想,想把最近主流的编程语言性能作个简单的比较, 至于怎么比,还是不得不用神奇的斐波那契算法。 2017年的golang、python、php、c++、c、java、Nodejs性能对比 续集更新 本人在PHP/C++/Go/Py时,突发奇想,...
还有权威对比: https://benchmarksgame.alioth.debian.org/u64q/go.html 原文 https://blog.famzah.net/2016/09/10/cpp-vs-python-vs-php-vs-java-vs-others-performance-benchmark-2016-q3/ 大家看看就好。 最后,就是加个大图,说明一切 但是图中没有算compile时间,对动态语言不公平。 另外, 性能相差不大...
Rust's performance is outstanding and comparable to C and C++, which are often regarded as the highest-performance compiled languages. Unlike these older languages, Rust offers memory safety and concurrency safety at essentially no cost in execution speed. It’s far more efficient in executing algo...

the buffer is allocated in a single block of memory along with the containing struct and no indirection is required. For systems programming, this design can have a better performance as well as reducing the number of items known to the collector. At scale it can make a significant difference...
