Hello, having installed Mathematica 7.0.1 (Student edition) for Windows (Win XP SP3), I have noticed that as soon as the MathKernel.exe is loaded, my CPU usage goes up to 30% every 3 seconds. This behavior is visible when I leave my system idle, and I have observed it so far also on another Windows system. It didn't occur in the 7.0.0 version. Using the ProcessExplorer and ProcessMonitor tools, I found out that actually the system load is not directly caused by the MathKernel, but by a process called "svchost.exe" (of which there are typically many running in the background). The MathKernel (and svchost) constantly generate calls to the Windows Registry querying for example "HKLM \System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\" and some other possibly network related things. I find this behavior very annoying especially when you are working with a laptop... Does anybody else has experienced this?
