[Dpp-devel] Optimizing Code - Comments

[Stefan R. <sro...@ar...>]

Hi Folks,

Just noticed this by myself.

Please always add comments, when you optimize code that results in much 
more complicate code, but should not
be refactored because of an optimization.

I forgot this when I worked on 
http://sourceforge.net/tracker/?func=detail&aid=3515619&group_id=167540&atid=843359

Pre:

Let x be the directory length (in characters / byte (depends on 
encoding)). Let y the number files in this directory and let
z be the average length of a filename (in characters / byte (depends on 
encoding)).

Transmitted bytes ...

Pre optimization:

Bytes for all filenames in a directory: x * y * z

After optimization:

Bytes for all filenames in a directory: x  + (y * z)

Regards,
Stefan
