Except in some very specialized systems, this is not a real concern. IO-intensive Code vs. Computation-intensive Code The majority of typical enterprise applications are distributed, layered applications that involve a lot of input-output operations. This is especially true under today’s prevailing architectural paradigm of service-oriented applications. These I/O operations can be network communication, inter-process communication, file I/O, and so on. NET application’s execution stack might look like this: ❑ IIS receives petition from browser (network I/O) ❑ ASP page communicates with remote COM+ component (network I/O) ❑ COM+ component communicates with several other remote components (network I/O) ❑ Next COM+ component communicates with remote web service (network I/O) ❑ Next COM+ component writes to log (file I/O) ❑ Next COM+ component communicates with database (network I/O) Generally, I/O operation is by magnitudes slower than internal, computational operations.

Such optimizations might include tactics such as connection pooling, optimizing database query performance, and filtering data in the database versus filtering data in the client, and so on. This leads you to the next premise related to refactoring and performance. Application Performance Is Defined by Performance Bottlenecks, Not by Absolute Performance Once you have committed yourself to a certain platform, you should try exploit all the benefits it provides. You could write a procedural program in C#, but it doesn’t make sense.

Refactored code often includes ready unit tests that bring their own benefits to the refactoring process. ❑ Applications for which refactoring is put into practice often have better handled component-level dependencies, making them easier to deploy. Now let’s take a look at C# and how its modern language characteristics are well suited for the refactoring process. Com Chapter 1: Refactoring: What’s All the Fuss About? NET platform, Microsoft decided it was time to begin with a clean slate — a new programming language.
