Write vb.net code in page.aspx, or page.aspx.vb ?

Hello,
I would like from someone to explain is it better to write vb.net, or C# code inside of page.aspx, or behind page.aspx.vb(c#)?

My thoughts:
1.'m used to write vb.net, c# codes in page.aspx.vb(c#), and also sense is telling me, if Page.aspx has less lines, then pages are more quicly loaded ?!
2.But, in other side, if vb.net, c# codes are written inside of page.aspx, then codes are faster executed?!

False/True ?

Thank you in advance for help to anyone!

Coding c#/Vb .net using the code behind is always good

Code-behind refers to code for your ASP.NET page that is contained within a separate class file. This allows a clean separation of your HTML from your presentation logic

code-behind can be deployed in dll which works faster.

mycodebehind.aspx
mycodebehind.cs

Syntax to compile codebehind

csc.exe /out:mycodebehind.dll /t:library mycodebehind.cs

code-behind page inherits from the Page class

Inheriting from the Page class gives the code-behind page access to the ASP.NET intrinsic objects, such as Request and Response

you can reference the code-behind class by using an SRC tag
In this case, ASP.NET compiles the code-behind page on the fly.

When you use Microsoft Visual Studio .NET to create ASP.NET Web Forms, code-behind pages are the default method. In addition, Visual Studio .NET automatically performs precompilation for you when you build your solution. Note that code-behind pages that are created in Visual Studio .NET include a special page attribute, Codebehind, which Visual Studio .NET uses.

1. false, asp.net will join both aspx and code-behind(C#, vb) as one resource.
2. False, location is not important.
aspx and code-behind separation is done to allow developers to have a clear separation between User interface and code.

How you design your code  and our page contents will influence the performance.

as an extension to previous poster's comment, maintaining the seperation between the page design and the code will help keep your code cleaner and better organised, helping anyone who has to support your page.
It also makes it a little easier to copy code into other projects ;)
