We recently purchased DPA and have it pointed at several SQL Servers. On some servers it is responsible for up to 30% (or more) of our waits. One sql statement in particular,
[tempdb].[dbo].[RG_WhatsChanged_v3] , sticks out.
What load is typical for DPA on a server. Ours are particularly under resourced, so I think this behavior I'm seeing is symptomatic of that. thanks
