RUM client processing slow - device cleanup needed?

Hey guys,

we are just in the middle of an AD migration project. We already have moved the smaller branch offices and everything worked fine so far.
Now we are heading for the bigger bunch and in some cases I have seen that the RUM client processing was very slow.

I know the performance is depending on the hardware capabilities of the client, if you use the agent and on the amount of files of the user.

So I already searched the knowledge base, but I have not found a description, which files are touched during the processing.

Is it just C:\users\John.Doe for the corresponding profile, or even more?

I'm asking, because I just want to consider if there is a possibility of cleanup before the migration.

Thanks in advance.
