测量特定计算机 LAN 网络速度的简单方法？
我想测量局域网上两台电脑之间的网络速度。 （我正在考虑购买网络区域存储 (NAS) 设备，我想看看当前设置的速度有多快，以了解 NAS 需要多快。
我想我只需复制一些文件看看这需要多长时间，但我认为可能有一种更精确的方法来衡量。
I want to measure the network speed between two PCs on Local Area Network. (I'm thinking of getting a Network Area Storage (NAS) device and I want to see how fast the current setup is to get an idea of how fast the NAS needs to be.
I'm thinking I'll just copy some files and look at how long that takes, but I thought there might be a more precise way to measure that.

要测量网络性能，iperf 是我见过的最好的工具。
但是，我不认为这对解决您的问题有帮助。 您无法根据网络性能来确定 NAS 解决方案的规模。
使用与 NAS 相同的协议传输文件对于这种情况肯定更相关。 仍然没有帮助。
您可以假设任何现代机器都可以以超过 90% 的链路速度传输数据。 （无论是否涉及本地存储，除非存在问题或重大其他负载）。
十几个相当现代的客户端应该能够摧毁相当强大的 NAS。 您确实需要模拟现实世界的负载。 这基本上是不可能的。
您需要从不同的角度来调整 NAS 解决方案的规模。 客户的能力确实不相关。
To measure the network performance, iperf is the best tool I have seen.
I do not believe this will be helpful in solving your problem, however. You aren't going to be able to size a NAS solution based on the network performance.
Transferring a file using the same protocol the NAS would is certainly more relevant for this case. Still, not helpful.
You can assume that any modern machine can transfer data at over 90% of the link speed. (whether involving the local storage or not, unless there's a problem or significant other load).
A dozen reasonably modern clients should be able to crush a fairly powerful NAS. You really need to simulate real-world load. That's basically imposssible.
You need to approach sizing your NAS solution from a different perspective. The capabilities of the clients really aren't relevant.
如果您在另一台计算机上执行相同的过程，这可能会起作用。 可能不准确，但可以提供一个想法。
This might work if you do the same process with another computer. It might not be precise, but could give an idea.
每个 NAS 设备往往都会生成吞吐量数据作为其规格的一部分。 一般来说，如果考虑速度，您最好选择 SAN 而不是 NAS。
Each NAS device tends to produce as part of its spec a throughput number. Generally speaking if speed is of concern, you would be better off which choosing SAN over NAS.
