<p>Created page with &quot;= KVM slow with win 2008 server installed with ms sql = Apparantly MS implemented a new timer system on sql servers which makes the host cs 1024/sec. This is quite annoying and …&quot;</p> <p><b>New page</b></p><div>= KVM slow with win 2008 server installed with ms sql =<br /> Apparantly MS implemented a new timer system on sql servers which makes the host cs 1024/sec.<br /> <br /> This is quite annoying and will up your cpuload from having to switch constantly alone.<br /> <br /> Easy fix is to disable the new timer system and revert to the old.<br /> <br /> A workaround is listed here:<br /> <br /> &lt;pre&gt;<br /> http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c02110402&amp;lang=en&amp;cc=us&amp;taskId=101&amp;prodSeriesId=3896111&amp;prodTypeId=3709945&amp;aoid=35252<br /> &lt;/pre&gt;<br /> <br /> In my case it brough the guest down from ~30-40% constant cputime to about 5-10%.</div>
