High CPU when changing network to NAT

Description
Hi,
Host is Win XP SP3, Guest is Windows Server 2003.
Start the VM as bridge, when OS is running, change the network connectivity to NAT.
Any request to the Internet (e.g. IE) will push up the CPU to 100% use up to 7 ou 8 seconds.
Setting back to bridge connectivity will get back to normal.

Hello,
I have made an regression to v3.1.4, the version v3.1.6 seems to consume a lot of CPU.

"use up to 7 ou 8 seconds" does it mean that cpu usage up to 100% for 7-8 seconds ant then calm down? What happens if start vm with NAT networking?

Yes, when changing adapter type and using NAT consumes a lot of CPU (e.g. browsing on the web and using Numara Track-It! Server / Client) when compared to Bridge.
I have made an regression for 3.1.4, which seems more stable in my environment (notebook Asus M50SV) and consumes a lot less CPU.
