Mac OS sierra - update from el captain -- Slow SMB performance with Qnap thunderbolt NAS

hi
I just updated form el captain to sierra ( Low) to maybe overcome a MXF export issue in el Captain . i get errors in the MXF XDCAM HD file on Experting and also with compressor

BUT. the connected QNAP thunderbolt NAS ( TVS-871T) is much slower in sierra
Multicam clips that play fine on Capital now stutter . i am very disappointed and looking for Help. the dates in the NAS are also messed up again ( 2022 )

anyone has any ideas or experienced similar ? also on the MXF export issue ?
Thanks for any help . i think i have to downgrade
regards peter

MAC pro 2013, el captain 11.6 before now 12.6. fop x 10.3.4
