I have few global methods declared in public class in my ASP.NET web application.

I have habit of declaring all global methods in public class in following format

public static string MethodName(parameters) { } 

I want to know how it would impact on performance point of view?

1. Which one is better? Static Method or Non-Static Method?
2. Reason why it is better?

Following link shows Non-Static methods are good because, static methods are using locks to be Thread-safe. The always do internally a Monitor.Enter() and Monitor.exit() to ensure Thread-safety.

And

Following link shows Static Methods are good static methods are normally faster to invoke on the call stack than instance methods. There are several reasons for this in the C# programming language. Instance methods actually use the 'this' instance pointer as the first parameter, so an instance method will always have that overhead. Instance methods are also implemented with the callvirt instruction in the intermediate language, which imposes a slight overhead. Please note that changing your methods to static methods is unlikely to help much on ambitious performance goals, but it can help a tiny bit and possibly lead to further reductions.

I am little confused which one to use?
