Ok, so I installed Win 10 on Virtualbox 5.2.16 on my machine and I can
confirm Jan's findings; in NAT mode the ideal backlog stays flat at 64
KB, and the patch provides no benefits.
Once I switched to "Bridged adapter", I got normal results (as in,
similar to what other people reported):

Microsoft Windows [Version 10.0.17134.112]
generating test file...
running vanilla...
start:0.687000 total:6.062000
running patched...
start:0.625000 total:2.407000

Looks like a limitation of VirtualBox's NAT mode.

Daniel
