In solrconfig.xml, change the dismax parameter "q.alt" to something besides '*:*'. Hitting this query by accident can also make a large index unavailable for minutes.

trying to extract possibly useful suggestions from the docs:

I don't see this as a task. Perhaps an issue for collecting useful information for users with large indexes? As the links suggest, performance issues will very likely be different from one site to the next. If there is a specific performance problem with the implementation of the module, we should open a specific ticket for that. I don't understand why having q.alt set to *:* is a problem.
