Hi, I have a M2 Pro Mini connected to a PC via a CAT6 ethernet cabe and the built-in 10GbE port in both computers. For internet, both are connected via WiFi. When I smb to the PC from the Mac and dragged and dropped a file from the PC to the Mac desktop, it took about 1GB/s. How do I get close to 10GB/s?
Got a tip for us?

Slow 10GbE ethernet connection between M2 Pro Mini and PC

Thanks. Maybe I mixed up.
I just double checked:
File size: 2.69GB
So 2.69GB (Gigabyte) is the same as 21.52Gb (Gigabit). In the best theoretical case, it would take 2.152 seconds to complete the transfer when both computers are connected via their respective 10GbE port and an CAT6 cable. Am I correct?
I ran five trials but they showed very different in speed.
1. 00:03.03 (don't remember the settings used)
2. 00:02.76 (setting: manual, Duplex: full duplex, MTU, Jumbo 9000)
3. 00:02.70 (setting: manual, Duplex: full duplex, MTU, Jumbo 9000)
4. 00:19.66 (setting: automatic)
5. 01:45.58 (setting: manual, Duplex: full duplex, MTU, Jumbo 9000)
So Trials 2 and 3 are as best as it could get?
What caused the very long transfer speed in Trials 4 and 5?

Hard to say what's going with #4 and #5. Could be SSD cache filling up? But yeah if you can transfer a 2.69GB file in <3seconds, you're doing great.
You're stuck with what you have under macOS. The performance in Windows is determined by the particular drive characteristics.
I can't say 100% that this is the source of the slowdowns you're seeing, but it would make sense. After the SSD runs out of SLC cache, it slows waaaaaaay down.

Currently my Mini is M2 Pro with 16GB and 1TB SSD. How likely will I see even worse performance if I go for a M2 Mini with 16GB and 256, 512 or 1TB SSD? For backup, I will use an external SSD.
Even Apple Tech Support people have no idea the detailed specifications of the SSD. Asked a few of them already.

Don't all the Apple Silicon Macs have SSDs at least as fast as 1 GB/s?
Did you try doing the file transfer in the opposite direction, from Mac to PC?
Did you try doing the file transfer in either direction using Windows instead of Mac OS?
Try using Crystal Disk Mark on Windows or AmorphousDiskMark on macOS to see max read/write sequential speed, bypassing the Finder or Windows UI.

I don't think the problem is on the Apple side, it's the 'destination' Windows PC.
Some of these things are software/hardware inhibited and beyond the user's control.
Max transfer rate of 10Gbps link speed is a little more than 1GBps.
Yup, this is crazy fast. I would love those transfer speeds.
Easiest way to do a general test is to run a blackmagic speed test to the PC using SMB.
