如果家里接上了万兆宽带/光纤,那么到底什么才是影响你电脑网速的关键呢?

在PCworld的最新测试中就试图探讨下这个问题,最后发现,硬盘和CPU很有可能拖后腿。

 

对于网速,很多人自然想到的是网络设备要满足,包括光猫、路由以及网卡等。所以测试先确保这三点满足要求,比如网卡用的是Intel 82599EN控制器10G PCIe SFP+。

在先后在网络畅通的凌晨3点下载一款22GB的Steam游戏与5GB的Win11官方ISO后发现,10TB的希捷SATA硬盘每次都是最慢的存在。

鲜明对比的是,写速2.7GB/s的Intel傲腾SSD每次都是最快完成,22GB的游戏更是2分多钟就搞定。

万兆宽带实测:给网速拖后腿的居然是电脑CPU和硬盘

同时,可能会被很多人忽视的一点是,CPU配置同样会影响到网速发挥。

测试者将一颗酷睿i9-7980XE(18核36线程)分别配置到双核、四核、六核、八核、十二核、十六核工况下,尽管匹配的是手头最快SSD,可随着打开核心数的增多,峰值写速会随之水涨船高。

所以说,万兆带宽包括千兆考验的不仅是你的网络设备、布线等,也千万不要让硬盘、CPU成为被忽视的瓶颈所在。

If the home is connected to 10 Gigabit broadband/fiber, then what is the key to affecting the speed of your computer?

In PCworld’s latest test, I tried to explore this problem, and finally found that the hard disk and CPU are likely to be dragged back.

 

For the network speed, many people naturally think that the network equipment must be satisfied, including optical modems, routers, and network cards. So the test first ensures that these three points meet the requirements. For example, the network card uses Intel 82599EN controller 10G PCIe SFP+.

After downloading a 22GB Steam game and a 5GB Win11 official ISO at 3 a.m. when the network was unblocked, I found that the 10TB Seagate SATA hard drive was the slowest every time.

In sharp contrast, the Intel Optane SSD with a write speed of 2.7GB/s is the fastest to complete every time, and a 22GB game is completed in more than 2 minutes.

At the same time, a point that may be overlooked by many people is that the CPU configuration also affects the performance of the network speed.

The tester configured a Core i9-7980XE (18 cores and 36 threads) under the working conditions of dual-core, quad-core, six-core, eight-core, twelve-core and sixteen-core. As the number of open cores increases, the peak write speed will increase.

Therefore, the test of 10 Gigabit bandwidth, including Gigabit, is not only your network equipment, wiring, etc., but also do not let the hard disk and CPU become neglected bottlenecks.
