High CPU and memory usage after Add-in update to 11.2.385.0

After Connect Add-in update 11.2.385.0, high CPU usage are observed on some of the Windows OSes. This is because of a new functionality added to log the add-in performance. The data is collected using the “process” counter. The issue is because this counter is disabled on some of the systems.

As a workaround the performance monitor library needs to be rebuilt and “perfproc” provider should be enabled as follow:

Click Start, type cmd right click cmd.exe, and select Run as administrator.

At the prompt, type lodctr /r and press ENTER. This will repair the pointers (those are stored in the registry).

 

C:\Windows\system32>lodctr /r

Info: Successfully rebuilt performance counter setting from system backup store

 

After this action it is possible that perfproc providers are disabled. You can check the status with lodctr /q.

 

C:\Windows\system32>lodctr /q

Performance Counter ID Queries [PERFLIB]:

etc…

 

If it says (Disabled) next to perfproc  provider, you can enable it with lodctr /e:perfproc

This should fix the issue for Windows OSes on English locale. Unfortunately, for other locales, this workaround will not work. Next add-in update will have the fix for this issue.
