LO has a reputation as an IDE-killer, as it’s so large and complex.

This doesn't seem to be worse than the Unreal codebase, which 10x also handles with ease. I highly doubt that there is a codebase in existence which could bring 10x to its knees. It does use quite a bit of memory, but nothing a modern setup shouldn't be able to handle. Currently it seems to be about 4GB for both Unreal and LO each, with LO being just slightly larger.
This of course are extreme cases, so you can imagine what performance for "normal" projects is like.
I only signed up because I saw a lot more questions than people reporting their experiences with it, so I figured you would like to hear from people who actively use it (and why). Some of us then prodded Stewart (the dev) to also sign up so he could answer the more specific questions.
