Custom Plugins Performance

Question for developers who end up writing their own custom plugins for sites. Is it better to combine them all into 1 plugin and just call the sub-routine when you need that functionality regardless if they have any relationship to each other? Or better to separate those functions into their own plugin folders?

I assume part of that depends on your team size and the ease of maintainence, but I’m going on the assumption that having less files/folders equals better performance.

Example 1: Function 1: exp:function1 Function 2: exp:function2

Example 2: Function 1: exp:my_plugin:function1 Function 2: exp:my_plugin:function2

This is primarily for plugins only.
