postgres does not respond to a query view of 10000 records roughl y

Hi, I developing a program usinn postgres and linux like system operation. My problem is this:
I have a view quite complicated with roughly 10000 record. When I execute a simple query like this
        "select * from myview"
postgres does not respond and does not produce any results. I hope that someone can help me with some suggestion about reason of this behavior and some solution to avoid it. Thank you for your attentions and I hope to receive some feedback as soon as possible
