Help Understanding LAN test Speed Results
-
I ran a LAN Test speed using from a client to a server, which are both in the same LAN as it's a small dental office network. The results are showing 67.88Mbps (Writing/Upload) and 405.51Mbps (Reading/download). I don't know what their physical infrastructure is as I work remote, but I'm sure it's 1Gbps Ethernet. If that's the case, does this test result indicate there's an issue, with the huge difference between upload and download, all in the local LAN?

What did you use for the speed test?

LAN SPEED TEST made by Totusoft.

Most likely there is a drive speed limitation on the write.

I originally thought this - but then, if he's using a utility to send data to the server, I would assume that would be done in RAM, but could be wrong.

What should a good lan speed test look like from a client to server?

This isn't an easy question to answer.
for a test that's 100% RAM, it should max out the connection, so Gbit should be 950 or could be more, but once you start throwing disks into the mix, you can drop significantly...

Try iPerf. It definitely puts storage out of the equation. Try using it with parallel threads to get more accurate results what the link can really handle. Also, it would only test TCP throughput by default but you can test UDP on a client side with -u switch. There are tons of guides on it online.

I did use iPerf and the results were within range of 900Gbit/s, which is what I wanted to know. Seems like the Lan Speed Test tool I used prior was slower due to the hard drive write times of the client, which makes sense, since I had to put a folder path to the server share.

Yes, use iPerf. It's the industry standard for this kind of stuff.

another vote for iperf3
even better 'cause it's available via chocolatey -

That the test is labeled writing / reading.... then yes, you're expected to be testing a lot more than the network and a big difference would be expected.
