Speeding up Unreal Editor launch by not spawning unused tooltips

Kinda annoying that the article doesn't really answer the core question, which is how much time was saved in the start up time. It does give a 0.05ms per tooltip figure, so I guess multiplied by 38000 gives ~2s saved, which is not too bad.

"Together, these two problems can result in the editor spending an extremely long time just creating unused tooltips. In a debug build of the engine, creating all of these tooltips resulted in 2-5 seconds of startup time. In comparison development builds were faster, taking just under a second."
