Provide technical guidance on common needed workarounds for deduping
Medium sized sites of 10k - 50k contacts not uncommonly run into timeouts and similar problems when trying to use dedupe rules. It would be helpful to indicate in the documentation common workarounds, tuning parameters, etc.
For example, on the Dedupe stuff I think some heuristic rules of thumb for how to tune a site so that one can tune deduping parameters in case of timeouts would be appropriate. So, up PHP max timeout. Increase your RAM. In a db with 10k contact using first name and last name and 60s, choose a group no bigger than XXX contacts.... This is a very common problem.
