多么强大的移动浏览器相比，台式机？ [英] How powerful are mobile browsers compared to desktops?

问题描述

我计划实施我建立一个应用程序的一些客户端的散列（或许加密）。使用斯坦福大学的Javascript加密库在桌面上的需要的过了一分钟的做一些计算，我要求浏览器在JavaScript中执行。

I plan on implementing some client-side hashing (and perhaps encryption) for an application I am building. Using the Stanford Javascript Crypto Library on a desktop takes over a minute to do some of the calculations I'm asking the browser to do in Javascript.

我想知道，如果这是要求从像丝绸，移动Safari和其他移动浏览器太多了。除了测试上最先进的智能手机 - 有没有什么太多对他们的一般准则？他们是桌面浏览器多么强大的比例是多少？

I'm wondering if this is asking too much from mobile browsers like Silk, Mobile Safari, and the others. Apart from testing on most modern smart-phones - is there a general guideline of what is too much for them? Any ratio of how powerful they are to desktop browsers?

推荐答案

这真的取决于你的目标市场。我最近买了一台HTC One X的安装和Mozilla Firefox浏览器，以及Chrome测试版....我已经与基于HTML画布的游戏测试，他们俩它执行得非常好。

This really depends on your target market. I've recently bought a HTC One X and installed Mozilla Firefox, and the Chrome Beta.... I've tested them both with HTML Canvas based games and it performs surprisingly well.

结论1。
这样就完成了高端笔记本电脑和高端移动设备之间的一般JavaScript性能差大约7到8折。

Conclusion 1. This concludes the general JavaScript performance difference between a high end laptop and high end mobile device is approximately 7 to 8 fold.

2结论
就这样结束使用斯坦福的JavaScript加密库大约是4〜5折高端笔记本电脑和高端移动设备之间的性能差异时。此外，在这些测试中把这个移动设备上的时间是在我看来，可以接受的等待时间。

Conclusion 2. This concludes that when using 'Stanford JavaScript Crypto Library' the performance difference between a high end laptop and high end mobile device is approximately 4 to 5 fold. Also The time in which these tests took on this mobile device are in my opinion acceptable wait times.
