hi,

when copy file remote folder local, file firstly loaded ram  - see high copy speed ram has faster i/o nic.

as file large, ram cannot cache whole file, cache part , writing disk - speed go down until next time load part ram.

from screenshot have 16gb ram large. there still part of ram waiting other process not ram using copying files.

you can open performance monitor see hard disk i/o see if bottleneck of copy process. 


please remember mark replies answers if , un-mark them if provide no help. if have feedback technet support, contact tnmff@microsoft.com.
