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.
