Whenever I try to run a simple query on a production database table, I get a timeout 504 error. I'm using the SQL interface in Ensemble. One of the queries is a simple SELECT TOP 10. Even SELECT COUNT(*) gives a timeout.  I have tried to run the SQL Runtime Statistics, but this gives me a timeout as well.  Does anyone have an idea where I might look to find what is causing this?    Thanks in advance,  Best regards Glenn van Bavel,
