Speed difference between copper and optical 10G connections
We have a QNAP server connected optically and then clients connected optically and copper. With the copper clients we have pretty similar read and write speeds to the server - with the optical ones t...
The QNAp is optical also.. The thing is that the 10G copper connectivity works much better than the optical.. All the PC are basically the same.. z840 win 10 and all the optical conected ones perform worse than all the copper connected.. There is a few different types of cards in both optical and copper but the optical ones read performance is always much worse than any of the coppers.
So it feels like the optical/copper cards and the PCs aren;t to blame.
Typically optically we get 600M upload but less than 200 m download
Copper we get about 500M both ways..

If this would be a switch fiber port issue, the "slow" download to the PCs would be also a slow upload to the QNAP, isn't it?
That's why I've requested details of the fiber cards on the PCs.
