In my experience, latency is the big buzzkill for CIFS. It seems like any
latency will slow things down, and the more you have, the worse it gets. I
assumed this has something to do with TCP window size, but I don't know.

If it were my setup I would try disabling scrub just to see what the effect
is on transfer speed. If you see a difference then it gives you a place to
start.
