When one article is transcluded in another, opening the transcluding article means that the rendering engine (which runs on the server) has to parse the transcluded article to look for transcluded sections, then paste those sections into the transcluding article, then render the HTML for the whole thing.

Does it take longer? Yes, because you're making the server read and parse several articles instead of just one. That's why there's a limit to how many transclusions the engine renders for any one page.

Does it increase the load on the client? No.
