SMB Mount (NAS) at login (no matter whether it's done via script of login item) SUPER slow (25MB/s). If I unmount and remount, I get expected speeds (700MB/s). I know SMB in macOS is hot garbage, but this is insane! Any thoughts?

Tacticals: Server: Mac Studio M1 (10GB CAT6A SFP+) NAS: Synology DS1821+ (10GB fiber SFP+) Switch: USW Pro 24 PoE Gateway: USD-Pro Server OS: macOS 14.7.3 (rolled back because 15.x was a friggin' nightmare for mounted shares) Both SFP connections are set to auto (MTU: 1500 - no jumbo frames) Before I create a script that will mount, unmount, and mount again, wanted to see if I am missing anything.
