64 位版本的Internet Explorer 9一直在那里，安装在我的电脑上很长时间了，我从来没有费心去检查它。我知道它没有任何插件，并且某些网站在它上运行不佳。但与此同时情况发生了变化，插件问题^{(plugin problem)}也消失了。因此，我决定试一试，看看效果如何。首先^(First)，我花了一些时间运行了一些基准测试，将其与 32 位版本进行比较，看看是否有任何性能提升^{(performance gain)}。阅读这篇文章以了解我的发现。

用于测试的基准

我决定进行以下基准测试：Peacekeeper、SunSpider JavaScript Benchmark、V8 Benchmark Suite和HTML5 test。

我使用我的个人台式机进行这些测试，硬件配置^{(hardware configuration)}如下：AMD Phenom II X4 905 (2.5 GHz ) 处理器，技嘉 GA-MA785GT-UD3H 主板^{(Gigabyte GA-MA785GT-UD3H motherboard)}，内存为Corsair XMS3 DHX 6GB DDR3 1600 MHz，技嘉 Radeon HD6870 OC 1GB ^{(Gigabyte Radeon HD6870 OC 1GB)} DDR5^{(DDR5 video)}显卡，120GB RunCore Pro V 2.5" SATA III SSD 驱动器^{(SATA III SSD drive)}。

除了HTML5 测试^{(HTML5 test)}之外的所有基准测试都运行了 3 次，我计算了平均分数。

Internet Explorer 9 64 位与 32 位

您可以在下面看到我为每个基准测试获得的结果。如您所见，情况相当复杂。

在Peacekeeper中，性能提升^{(performance gain)}了 2%，而在V8 基准测试^{(V8 Benchmark)}中，性能提升仅为 0.9%。Sunspider 基准测试^{(Sunspider benchmark)}是唯一惩罚 64 位版本的，它比 32 位版本慢 1.2%。

HTML5 测试^{(HTML5 test)}查看您的浏览器对HTML5标准^{(HTML5 standard)}和相关规范的支持程度。该测试仅证实我们在两个版本的浏览器中具有相同的标准合规性^{(standard compliance)}，这并不奇怪。

有结论吗？

很明显，性能增益^{(performance gain)}（如果存在）非常小。很可能您在浏览网页时甚至都不会注意到它。因此，如果您想要更快的浏览体验^{(browsing experience)}，64 位版本的Internet Explorer 9将不是一个很好的选择。

就个人而言，我认为是时候提供更多 64 位浏览器了，能够提供更快的网络浏览体验^{(browsing experience)}。这就是为什么我想继续测试 64 位版本的Internet Explorer 9并返回至少一篇关于使用它的真实体验的文章。

Does the 64-bit Version of Internet Explorer 9 Deliver Better Browsing Performance?

The 64-bit version of Internet Explorer 9 has beеn sitting thеre, installed on my computеr for a long time аnd I never bоthered to check it out. I knew that there weren't any plugins for it and that some websites would not work well on it. But things have changed in the meantime and the plugin problem has disappeared. Therefore I decidеd it to take іt for a sрin and see how well it works. First, I spent some time to run a few benchmarkѕ, compare it to the 32-bit version and see if there is аnу performance gain. Read this article to learn what I have found.

The Benchmarks Used for Testing

I decided to go for the following benchmarks: Peacekeeper, the SunSpider JavaScript Benchmark, the V8 Benchmark Suite and the HTML5 test.

I used my personal desktop to make these tests, which has the following hardware configuration: an AMD Phenom II X4 905 (2.5 GHz) processor, a Gigabyte GA-MA785GT-UD3H motherboard, the memory is Corsair XMS3 DHX 6GB DDR3 1600 MHz, a Gigabyte Radeon HD6870 OC 1GB DDR5 video card, an 120GB RunCore Pro V 2.5" SATA III SSD drive.

All the benchmarks except the HTML5 test were ran three times and I calculated the average score.

Internet Explorer 9 64-bit vs 32-bit

Below you can see the results I obtained for each benchmark. As you can see, the picture is rather mixed.

In Peacekeeper there is a performance gain of 2%, while in the V8 Benchmark the gain is of only 0.9%. The Sunspider benchmark was the only that penalized the 64-bit version, which was 1.2% slower than the 32-bit version.

The HTML5 test looks at how well your browser supports the HTML5 standard and related specifications. This test only confirmed that we have the same standard compliance in both versions of the browser, which is not surprising.

Is there a conclusion?

It is obvious that the performance gain (when present) is very minimal. Most likely you won't even notice it when browsing the web. Therefore, if you want a speedier browsing experience, the 64-bit version of Internet Explorer 9 won't be much of an alternative.

Personally, I think it is time that we had more 64-bit browsers available, able to deliver a faster web browsing experience. That's why I would like to continue my testing of the 64-bit version of Internet Explorer 9 and come back with at least one more article about the real experience of using it.
