Network speed of 10Gb is fast and reliable.

Do you have backup cables? Have you attempted to change them? If the issue began shortly after the move, it might indicate cable damage.
There are four identical computers linked to a 10Gb connection, all sharing the same switch with the NAS.
Sure, I'll remove all the cables from that 10Gb switch. Just let me know if you need anything else and the Synology can be connected afterward. Thanks!
It seems the issue occurred suddenly after a previous stable state, making it hard to attribute it to client behavior. The server NIC might be the cause. Could you share what the performance was like before and which RJ-45 NICs are currently in use?
Have you explored running iperf on the clients? If they're on Windows, testing between two Linux systems connected via USB might help pinpoint OS-related issues. I should mention I faced similar challenges using LACP bonding on Gigabit ports—speed matched expectations before.
So we have another server connected via 10Gig NICs, not the switch. It matches the same speed as Iperf tests. The Intel X540-T2 cards were used for workstations. Running Iperf between two stations didn’t confirm this, so it’s possible the settings are off. Here are the configuration details for the workstation NICs: Rx & Tx Enabled, Header Data Split Disabled, Interrupt Moderation Enabled, Interrupt Moderation Rate Set, IPsec Overload Auth Enabled, ESP Enable, IPV4 Checksum Overload, Rx & Tx Enabled, Jumbo Packet Off, Large Send Offload, V2 Enabled, Local Administered Address 0, Local Link State Event Enabled, Low Latency Interrupt Ports Disabled, NA Interrupt Ports Disabled, Max RSS Queues 8, Packet Priority & VLAN Enabled, Received Buffers 512, Side Scaling Enabled, Speed & Duplex Auto Negotiation, TCP Checksum Offload, RX & TX Enabled, Transmit Buffers 16384, UDP Checksum Offload Enabled.
