GetConnectionUnixUser

[Tanner, Brad (EXL Ft Collins)]

We use externalsensor to host dbus objects and publish the values with custom code. During busy times on our BMC, the Property Set method takes a long time to complete. I noticed with monitor that every Set is accompanied by a method call to GetConnectionUnixUser, which must complete before the response to the Set is sent. It may be

Is there a way to prevent this extra dbus traffic?

Thanks,
