RE: Analyze

I had a similar problem last week. A program which ran quite quickly had become a dog. It turned out that a table which holds intermediate results was analyzed while populated. This resulted in a change in the query_plan and very slow results.
Dropping the statistics on the itermediate results table fixed the problem.
