How does Signature impact performance or memory usage?

Signature in programming refers to the method signature, which includes the method's name, parameters, return type, and any access modifiers. The impact of method signatures on performance and memory usage can be significant, especially in large applications.

When a method's signature is consistent throughout an application, it promotes reuse and can reduce the overhead associated with method lookups and calls. However, if there are many overloaded methods or a complex inheritance structure, the performance may degrade due to additional resolution time during method invocation.

Furthermore, memory usage can be affected by the number of unique method signatures that need to be loaded into memory. Each unique method signature can consume additional memory for maintaining the method metadata.

Overall, optimal usage of method signatures can lead to better performance and lower memory consumption, while poor design can lead to the opposite effects.
