Command line hangs after file transfer


I am new to TrueNas and was wondering why I have a long delay after the file has been reported to be transferred to NAS (refer to below terminal snippet below:
rsync --progress Downloads/livegui-amd64-20240526T163557Z.iso ./nas2/
3,513,456,640 100% 409.57MB/s 0:00:08 (xfr#1, to-chk=0/1)

after 100 percent is shown in the terminal rsync hangs for about 2 minutes.

My setup
wireless rsync file from a laptop over wireless AC speeds
TrueNas box is connected to a switch in a 4x1G lagg no Jumbo Frames
Ryzen 7 1700x
64GB Ram
TrueNas latest version
I have 2 sata based SSDs as a slog

Any clarification would be greatly appreciated and please let me know if further clarification is needed.
