I have a query in my application that takes an unreasonable
amount of time to complete (>4.5 hours execution time). After
reviewing the EXPLAIN and EXPLAIN ANALYZE output for that and similar queries,
my colleagues and I determined that turning off the enable_nestloop option
might help – we noticed dramatic speed improvements for that specific query
after doing so (<2 minutes execution time). I was warned not to mess
with the enable_XXX options in a production environment, but does anyone see
any problem with turning off the enable_nestloop option right before executing
my query and turning it back on afterwards? Bjorn Peterson Software Engineer (952) 681-3384 **************************************************************************** This email may contain confidential *************************************************************************** |
