ubuntu host web access is slower than windows guest vm

[Dazed_75]

Josh, the first problem I have with that solution is that it is 2 years and
4 ubuntu releases ago.  But a good explanation of the issues is buried in
https://help.ubuntu.com/10.04/serverguide/C/network-configuration.html

The section I refer to says:

> Name Service Switch Configuration
>
> The order in which your system selects a method of resolving hostnames to
> IP addresses is controlled by the Name Service Switch (NSS) configuration
> file /etc/nsswitch.conf. As mentioned in the previous section, typically
> static hostnames defined in the systems /etc/hosts file have precedence
> over names resolved from DNS. The following is an example of the line
> responsible for this order of hostname lookups in the file
> /etc/nsswitch.conf.
