Change Interval Between DRS Invocations

VirtualCenter activates the DRS algorithm after a fixed interval (the default is five minutes) so DRS can make recommendations based on the past performance metrics of the virtual machines in the DRS cluster. Although we recommend keeping the default value of five minutes, you can change the frequency by adding the following options in the vpxd.cfg file, changing 300 to the desired number of seconds.
<config>
….
 <drm>
 <pollPeriodSec>
300 <!--# of seconds desired between 60 and 3600 -- >
 </pollPeriodSec>
 </drm>

</config>
