Hi MikeC3964,
Yes, the "disabled" status is part of the config file content, so the UEM agent has to read all config files. Although the overhead of reading such a file is small (in your example log fragment each takes 4 milliseconds), it's best to remove the ones you don't need. This will also keep your log files a bit tidier, as they won't be full of "Skipping disabled ..." entries.
