July 5, 20242 yr I have to systems, Unraid & a PC, both equipped with their own 10gig nics. I am using a UDM PRO from Ubiquiti and a separate 10gig switch to link the two. Both devices (PC and Unraid) are communicating just fine... however sometimes my read and write speeds drop to around 300MB/s. This can be mitigated by rebooting the Unraid server. Not the switch, or the PC. The only solution is a reboot of Unraid. Obviously this is not ideal. To reiterate, I CAN transfer at 1GB/s however after an undetermined amount of time it will degrade to around 300MB/s. I've done the usual, set direct transfer to ON, isolated a share to be CACHE ONLY, and set the MTU on both devices to their maximum respectively (9000). I can't seem to figure this one out. I've also set both ports on the switch manually from AUTO to 10Gbit speeds. It very clearly seems Unraid related at this point. Diag attached. diag-20240705-0121.zip

July 6, 20241 yr So the issue appears to be the NIC/driver itself, or something directly related, can you point the timecode in the diags above where the issue started? Or post new diags and mention the timecode.
