Slow invoking of WCF service - performance

Question

So my issue is kinda simple but can't figure out how to deal with it.
I am using a wcf service which is accessing database through ADO.NET Entity Framework and after that I use this service to get the data in windows phone 7 application. The problem is when I call a simple select * from table the data gets populated in my WP7 for like 6-7 seconds which seems to me kinda long. I can post the web.config if needed but I havent changed much from what was generated from VS.
Anyone had the same issue or know how to deal with that?
I put my web.config, I thik problem should be there maybe.
