MySQLCancel may kill future query if the current one has already finished before the kill statement was issued Due to a bug in the MySQL Server, the kill query <PID> statement may kill a future query on this connection if the current query has already finished before the kill statement was issued.

User Interface (UI)


High CPU utilization is correlated to Record Presence transactions Analysis of servers with high CPU utilization has determined that Record Presence can significantly increase CPU load. It has been observed that turning Record Presence off can lead to a 25% reduction in CPU load.
  1. Toggle Record Presence off and on while hundreds of users interact with an app node.
  2. Notice the difference in CPU load.

Web Services


Extra call to getUser in HttpAuthProcessor may not be necessary and is generating 4 extra SQL calls on each inbound request Authenticating Web Service requests with user session/cookie information results in redundant SQL calls. In a very high volume use case such as Presence, this will negatively impact the performance of the request and the database.
  1. Log into a ServiceNow instance to create a user session.
  2. Turn on Debug SQL.
  3. Try to make a Web Service call, or wait for a Presence API request.
Note that 4 additional calls are repeatedly made to get user roles, licenses, and preference data on each request.
