In the past we’ve run diagnostics onto the db’s and found in the most part that the indexes we’d expect are in place.

One set of queries which we’ve seen to cause lots of rows being returned relate to when you have lots of languages and lots of versions as you get back fields for every permutation.

Such kind of SQL statements make the database to work well up to hundreds of records but can show noticeable performance drops when tables reac even thousands of rows! Not to speak when they accumulate hundreds thusands of rows or even more!
