10G Transfer speeds less than direct connection

Hello.

I recently purchased a XGS1250-12 managed switch in the home that I could setup my PC and NAS to the router so that all devices are available on the network and have access to the internet.

My PC and NAS have a 10G RJ45 port and I plugged the PC and NAS into 10G ports 10 and 11 on the switch. I then transferred an 11Gb file from my PC (on an SSD drive) to the NAS. The NAS have 6 disks in RAID 0 and is thus very fast.

During the copy, the speed shown went up and down a lot and the speed shown varied from 140 - 265MB/s

So for comparison, I liked the NAS up to the computer directly and after a bit of IP configuring, did a repeat test. The transfer speed in this case was much better, an almost constant line of 383-385MB/s

I didn't spend over £200 to get crappy performance on file transfer, so why is this happening?

    I have managed to solve it myself. I switched out one of the cat 6 cables and the performance is much better now.

    Hello @mickypen

    We did the local test with 2 desktops (both 10G NIC) connected to XGS1250-12 and the result is as below:
