Hi, Yes it is 4.0.1. But the first query has also to make a temporary table with 2 million rows, it's why I don't understand the delta between the query without DISTINCT and the query with DISTINCT. The "remove duplicates" doesn't occurs after the join was performed ?? (it should be really fast in this case)
