It's a piece of crap, but you're welcome to try to fix it up. See attached. With respect to the apparent lack of impact of the sleep loop, I can only speculate that this test case doesn't really mimic real-world conditions inside the backend very well. There is a lot more going on there - multiple locks, lots of memory access, etc. But I don't really understand it either. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
