PHP与JavaScript的速度？ [英] Speed of PHP vs JavaScript?

问题描述

我正在编写一个脚本来标记文件内容。我用JavaScript编写了一个tokenizer，但是对于大文件（5秒以上）来说它变得非常慢。因为我正在从服务器检索文件，我正在考虑用PHP重写它以减少几秒钟。我已经读过PHP和JavaScript之间的速度差异可以忽略不计，但是如果文件是1mb或更大，则速度差异可能会增加。我在网上找到了这个基准，但我不确定这些信息是否是最新的（所有信息都是最新的）过去几年的JS引擎优化）。

I am writing a script to tokenize file contents. I've written a tokenizer in JavaScript, but it gets pretty slow with large files (5+ seconds). Since I'm retrieving the files from the server anyways, I am considering rewriting it in PHP to shave off a few seconds. I've read that the speed difference between PHP and JavaScript is negligible, but if the files are 1mb or bigger, a small speed difference could add up. I found this benchmark online, but I'm not sure if the info is up-to-date (with all the JS engine optimizations from the past couple years).

移植我的所有代码需要一些工作，所以如果我能帮助它，我就不会使用PHP。但如果它会更快（25-30％），那就值得。

Porting over all my code would take some work, so if I can help it, I won't use PHP. But if its going to be much faster (25-30%), it would be worth it.

推荐答案

好吧，和你一样提到，JavaScript在客户端执行，因此它取决于客户端。例如，iPAD上的客户端将无法像在游戏机上运行的客户端那样顺畅地运行这些Quake3 HTML5。另一方面，PHP在服务器上运行。

Well, like you alluded, JavaScript is executed on the client side, so it would depend on the client. For example, a client on an iPAD wouldn't be able to run those Quake3 HTML5s as smoothly as a client running on a gaming machine. PHP on the other hand runs on the server.

一般来说，JS比PHP更快（在同一硬件上）;

In general, JS is faster considerably than PHP though (on the same hardware);

以下是两者之间的一些[硬数据] [1]测试，以支持我的断言。
