Postgres respond after toomany times to a query view

Hi, I am  developing a program using postgres and linux like operating
system. My problem is this:
I have a quite complicated view with roughly 10000 record. When I
execute a simple query like this       "select * from myview" 
postgres respond after 50 - 55 minutes roughly. I hope that someone
can help me with some suggestion about reason of this behavior and
some solution to reduce time ti have results. Thank you for your
attentions and I hope to receive some feedback as soon as possible

P.S.: Since I'm working with postgres for a small time I prefer a
detailed response, thanks
