Performance Gain when putting Meshes into Blueprints ?

Hello,
i have been wondering if there is a performance gain when putting up objects into blueprints instead of placing them directly. Basically my question would be, does it create an instance of all meshes inside the blueprint when placing the blueprint into the game world ?

Thanks!

The best thing you can do, use a cull volume, and set distances depending on mesh size (Doesnt work with blueprints though). The cull voluem then would remove meshes which become culled depending on the player position. Also you could use World Composition, and load different content from different maps. In regards to your specific question, i dont know but i doubt it.
