Hi Atlanticus - You may _still_ see high svchost usage, but with these new
components the machine should, however, remain responsive:
From a posting by Sudheer GN of Microsoft -
"Hi,
The biggest difference in WSUS 3.0 client (wrt performance) is that the
machines will still be responsive when WU client scans for updates. There
are also some optimization to reduce the number of update evaluations and
that will reduce the scan time in some scenarios.
It is still expected that CPU usage will be high so that the scan can
complete in lesser amount of time. But other applications can be launched
and used (they will still be a little sluggish because CPU is being shared
with WU client)

|| Hi Jim. That might be possible in my case. Thanks.
||
|| I installed the hotfix and update agent on 2 machines to test
|| without any custom hosts file in use.
||
|| For a P4 machine, svchost.exe/msi.dll will max out at 50% of cpu at
|| startup for a min or so, or if I run Microsoft Update manually, for
|| the duration of the update check.
||
|| For a celeron machine, svchost/msi.dll runs at about 70-90% of cpu at
|| startup for a minute or so, or when using Microsoft Update.
||
|| Moreoever, automatic updates do not often cause svchost to take up
|| resources at startup. It can be dormant for a few restarts too.
||
|| At least I don't see any 100% lockup and more leeway for other
|| processes to run concurrently but automatic updates can still take
|| up quite a bit of resources, esp. for slower machines.
||
|| Just some comments, if they are any helpful.

||| Hi Atlanticus - the most usual cause recently for the 100% svchost

|||
http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/WindowsUpdateAgent30-x86.exe

http://support.microsoft.com/?kbid=927891 for a complete fix.

http://www.mvps.org/winhelp2002/hosts.htm . If you are using a
