It's only a little bit faster which is surprising. Copying a 32 GB guest, with patch and without patch: real 7m21.136s real 7m36.794s The guest is a little sparse: 21623734272 62.9% 0 data 12736004096 37.1% 3 hole,zero Client and server are back to back over 1GB ethernet, and assuming we're copying around 21623734272 bytes, that's 392 Mbps with patch vs 379 Mbps without patch. Still investigating what's going on.
