结论1. 这就得出结论，高端笔记本电脑和高端移动设备之间的JavaScript性能差异大约为7到8倍

结论2.
这得出结论，当使用“斯坦福JavaScript加密库”时，高端笔记本电脑和高端移动设备之间的性能差异约为4到5倍。在我看来，在这个移动设备上进行这些测试的时间是可以接受的等待时间。
您的问题似乎主要是关于计算时间，因此我认为您的问题与移动浏览器的关系不大，而与移动处理器的关系不大。如果我不得不猜测的话，我会说，一般来说，无论你在桌面上做什么，都会比在移动设备上快4倍左右。如果在桌面上花一分钟（假设它是一个快速的桌面），那么在手机上花掉大量的时间。你在用这个加密库做什么？我已经在androids NDK中实现了SHA1，性能非常好。。比在JavaI中做同样的事情要好得多。我在我的应用程序中对不同的客户端内容进行了多次加密算法迭代（这些都与密码无关）。
