We upgraded our internal and edge Standard Lync 2013 servers to Skype for Business over the weekend and ever since we have experienced much higher CPU utilisation on the Pool server throughout business hours. CPU usage does drop down throughout evening and over night.
Task Manager shows SQL as (RTCLOCAL) as the highest user with SQL (RTC) and SQL (LYNCLOCAL) following. See the attached screenshots for more info. The specs of the server didn't change during the upgrade apart from increasing available space C:.
The user base or number of client connections hasn't changed.
Other than give the server some more CPU's what can we do to work out whey this is happening?
