I was just wondering whether it would be worth sticking to non-OOP code for the sake of speed. Also, In commercial web-applications, is OOP generally used or avoided? Which is the standard?

Many Thanks,

Ed

Answer 1

The standard is to favor readable code over efficiency, because most of the time "more efficient code" runs faster by a single millisecond. Object-oriented programming is generally more readable than a non-object-oriented counterpart.

Answer 2

OOP is generally used in commercial webapps, and is turning to be the standard. The reason for it is not efficiency - it's code re-usability, code readability, easy documentation, structure, and more importantly modularity!

Answer 3

Object-Oriented code is the standard, but not for performance reasons. It is really about maintainability.

Code speed is seldom of any real consequence in web applications. I/O is much more relevant, and most of the optimization people engage in is ultimately designed to reduce I/O:

• Persistent database connections
• Data fragment caching
• Page caching
• Client-side cache headers

Any significant CPU-intensive tasks are usually handled by compiled plug-ins, and made accessible to the interpreted language. Some common examples:

• PDF Generation
• Image manipulation (Imagik, GD)
• Cryptography (OpenSSL)

Answer 4

I think the OOP overhead is generally negligible for speed performance, and the code will gain much quality.

Commercial applications usually use OOP, if started after that was available (and stable!)
