I dont really like big plugins like jetpack. I find it much easier to manage multiple plugins with a single piece of major functionality rather than 1 plugin that does everything and use an options menu to pick what parts of the plugin to enable. I understand loading additional php files comes with an overhead, but this will be so small that its not worth considering. What i really want to know is if plugins by default have some kind of overhead. Will there is a notable difference between 10 individual plugins being loaded vs 1 plugin that has all the same code and functionality?
The best answer here is to just benchmark it, but it will take days for me to combine several plugins into one. I dont want to do this as its much easier to manage small plugins rather than having an options page where i can enable and disable parts on a massive plugin.
Whats the best approach to take here? The plugin i would be working on would be similar to jetpack. Large pieces of unrelated functionality that dont need to be combined unless there is a performance incentive.
