So the challenge is how to determine bottlenecks. Are there users on this list that have document runs of more than 10 seconds (as reference: the luametatex manual takes < 9 seconds for 350 pages and loads plenty fonts and has many tables) or have many (small) runs and are annoyed by the runtime? And if so, what does one guess are the bottlenecks?
