[development] How many modules is too many?

[Greg Holsclaw]

If the code volume (# of lines, kilobytes of file size) is the same,
then the memory imprint will not really be affected. But speed will
suffer since each file that has to be opened slows things down.

Drupal 6 will better optimize this issue by allowing module developers
to better include only the needed files through the menu system, thus
reducing overall memory usage without adding much overhead for opening
more files. I am sure chx would give a better summary.

I have the same question.  Does the number of modules enabled
significantly affect memory usage?

I tend to create tons of tiny modules, many of which do something
simple - like provide a single hook.  If the overhead from this
approach is significant, then I need to change my ways!
