SMB to/from a linux VM is pretty slow, I've spent time trying to optimize it. The performance hits bottlenecks in a few places including (if enabled) transport encryption. You'll have similar problems if you try to shuffle a few gigs across an ssh tunnel locally too (if you're sufficiently clever and willing to wield a compiler in anger, you can disable transport encryption entirely for a nice speed boost). For reference I had a situation where I needed to pull/push 1-2gb blobs across the VM boundary on a regular basis, so it ended up mattering a lot - sub-1-minute times vs 5-10 minute copies.
