I really don't know how it is possible. Connection from my SQL Express to the online database and doing query/etc is it so fast.
But, running the web application on localhost to the online DB takes very long time. Such as 20-30 seconds for a simple request. Watching the website online is so fast. So there aren't problem with the main application.
Connection string such as :
<add key="ConnectionString_ONLINE" value="data source=95.40.100.200,1900;initial catalog=DBName;USER ID=Username;Password=Password;" />
What could be the main cause?
