first of all best wishes at all from a new member in this forum.
As a fan of mikrotik products, i decided to install 3 crs 312-4c+8xg switches in our company, because our old 1G Switches weren't the best after a couple of years.
So i installed them in our network and our DELL R530 got an 10G Network Card (Dell (Intel) 10G X550-T RJ45 DUAL Ethernet Network CARD).
Now to my Problem:
If I transfer Files or make performance tests with iperf under Ubuntu theres a performance Issue with 1GBit Network Clients.
When i transfer Files from the Client to Server the speed corresponds to a 1G connection, but from server to Client i got a Max of 30M.
If i connect the same 1G Device direct to the server, then the connection is fast in both directions.
Maybe someone can help with this problem
thanks in advance
