Faster uploads to a ZFS network filler?

[joe mcguckin]

I have a FreeBSD 12.2 system running with SAMBA. Up loading large files (e.g. video files) I notice the first 700-800 Mb goes pretty quickly, but around 800Mb, it pauses then proceeds at about half or 1/3 
normal speed.

Is there a tunable parameter I can change to improve this behavoir? The server has plenty of memory, can I tell ZFS, SAMBA or the kernel to use more memory for caching?

Thanks!

Joe
