Structured Code vs. Performance

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I got different portions of code only used for certain purposes (who don't 
;-)?). But what, in your opinion (better: in your experience) would be the 
best regarding script-performance: Putting each code-portion in a separate 
file and include it if required, putting it in a constant-dependent 
if-structure (if (defined('FOO') && FOO) {class foo{}; function foo(); ...}) 
or simply let it be parsed every time?

My first choice is using separate files, but if a file e.g. only contains 20 
lines, I fear it would take much longer to include the file against simply 
parsing these lines in the existing file. And as parsing is done really 
fast, there might be no real performance-loss in case of not using the 
mentioned code. With the constant-dependent if-structure I don't know if 
there are any performance-benefits if FOO isn't defined or defined as FALSE.

Looks for me a bit like a philosophical question, but maybe you have 
something to say about it nevertheless. A good thing for me would be 
something like: up to 125 lines of code you get an adequate performance with 
simply parsing it every time, with more than 125 lines you would get a 
better performance with using separate files - just kidding, surely the 
number of lines in this case is 42 ;-).

Looking forward to your answers
Thomas
