DS918+ USB 2.5 GbE adapter, file transfer slow speed issue

Synology
1

I have DS918+ with a USB 2.5GbE adapter connected to LAN 3 network status 2500 Mbps, Full duplex, MTU 9000. with the static IP setup. Also, have a 2.5GbE NIC network card in the PC and a 2.5GbE network switch. I tried to connect without the switch (direct connection), and with the switch, my file transfer speed rate was the same as with the 1 gig network card; nothing changed (transfer speed 90.2 MB/s).

I tried everything nothing changed. I would appreciate your help. Please advise if there is something that Iā€™m missing. I watched all the YouTube videos and followed step-by-step instructions. Im confused. Please help.

Thank you.

I am not a fan of higher MTU setting, since all network devices (switch, PC) in the chain must support it or must be set accordingly. My first advice is to revert to the default MTU 1500.
