Does an installed, but unused, plugin reduce speed/use resources?

[robert]

If I have a plugin installed, but am not using an element or workflow or anything to trigger the plugin, will it still affect performance?

[gf_wolfer]

It may affect performance depending on the exact plugin. Here is some insight from Josh on the topic:

@josh

Plugins sometimes affect page load speed even if you aren’t using them. We often have to include the javascript to run the plugin as part of the page’s javascript whether or not you actually need that plugin, so my recommendation is if you know you aren’t using a plugin, to uninstall it.

Thanks @gf_wolfer

So, as a followup, can I uninstall a paid plugin, and later re-install it without having to re-buy it?

[gf_wolfer]

Hmm, not sure about that one. Might need input from @Bubble or others more experienced at adding removing plugins

[JohnMark]

Yes you can re install anytime, no cost.
