View & Procedure - SQL Server

Hello All,

I cant help but ask this question to all SQL Gurus here.

Recently I created a VBA application that calls a complex set of sql statements to show a data set in a certain way.
In order to accomplish the above, I tried doing it in two different ways...

1)I created a stored procedure to do the above
2)I also created a View to do the above.

I was tracking the seconds in the VBA application in terms of the time it takes to complete the command.

I found some real interesting info:

When VBA called the view from SQL Server, it took near to 1 minute
when VBA called the stored procedure from SQL Server it took 30 seconds

Why is this amazing difference ?

Is the stored procedure is better off than view in certain cases?
What are the advantages of using StoredProcedure ? Why would you want one, performance wise? like whats the real 'physics' behind it, that makes it preferable...if you get what I am saying..

Thanks
R
