Changes

Timing related options are important within Virtual Guests and to the amount of 'pressure' it puts on the host and level/increasing CPU usage of the host and guest. By default SME Server uses the NTP deamon for 'timing' related matters, but by default is focussed on the above mentioned 1000HZ, hence the kernel option 'divider=10', thus reducing the timing cycles/context switching requests on the host. See the above VMWare document mentioned (Way at the bottom).

SME Server has an undocumented feature related to the NTP deamon configuration (Please see [http://bugs.contribs.org/show_bug.cgi?id=5648 Bug 5648]). To activate the best NTP settings for a Virtual guest issue on the SME Server guest:

On a Virtual SME guest server the ntpd [[DB_Variables_Configuration#SupportLargeDrift|SupportLargeDrift]] DB variable can be enabled as follows:

 

  config setprop ntpd SupportLargeDrift enabled

  config setprop ntpd SupportLargeDrift enabled
