Re^4: package compiling

I'm sure I read somewhere that OO in Perl can slow down compilation and execution time by upto 40%... is that right?

What advantage would there to be gained from objectifying the code when all its meant to do really is act as a config file that doesn't need the processing overhead of parsing XML?

I ask in earnest, as I often wonder what people see in OO and why it seems to be taking over every language.

Sure, somewhere in a Java or Python forum ... ;-) OOP has a little overhead, but 40% looks like a very constructed example. And "up to 40%" could also mean zero. If you want to know, run benchmarks. If you want to know why your code is slow, use Devel::NYTProf. Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply]
