Network performance


Question

I tried looking around if perhaps someone had an issue like me, and seems like the suggestion made to that user was probably not valid as it was about changing MTU settings.

So here's my issue, when I download anything really from my xpeno server, I fully saturate my connection (1Gbps), but on the upload side of things I only seem to hit 500Mbps ish.

I did some benchmarking of my cpu\drives

Everything looks good as far as I can gather here. I have 8x 12TB Exos x16 in SHR2, 6 plugged via mobo (all sata3), and 2 via a JMB585 card.

I tried with a different computer, being my laptop but i dont have a native network port on it and i did try a usb-c adapter and the upload number were so awful I cant use it as a reference.
