Hi,
Just found out the Profitbricks help entry for VirtIO drivers installation for Windows. It recommends to do the following optimization:
Set the MTU Value to 6400
At a command prompt, execute the following:
netsh interface ipv4 set subinterface "Local Area Connection" mtu=64000 store=persistent Replace <local area="" connection=""> with the name of the adapter you want to configure.
Disable TCP Offloading / Chimney & activate TCP/IP Auto Tuning
At a command prompt, execute the following:
netsh int tcp set global chimney=disabled netsh int tcp set global rss=disabled netsh int tcp set global congestionprovider=none netsh int tcp set global netdma=disabled dca=disabled netsh int tcp set global ecncapability=disabled netsh int tcp set global timestamps=enabled netsh interface tcp set global autotuninglevel=normal
I also noticed that on Profitbricks Windows images these settings are different. So now I'm a little confused on what should be the right settings and the benefits (or not) of these.
Thanks for the help.
Nathan
