[NTG-context] Re: Why LuaMetaTex is so slow?

Hi Shiv, ConTeXt’s project structure has many benefits. One is speed. See https://wiki.contextgarden.net/Project_structure. My books and long papers are products, each containing many components (chapters or sections). When I’m working, I have both the product and a component open. I frequently typeset the component as I’m working. This is very quick. I only typeset the entire product if I intend print or send it, or when I need to check some product-wide element like references. Components can be nested, so take this approach to whatever extreme you desire. You can also use buffers if there are specific parts of your book (like diagrams) that demand significant processing. Buffers can save the typeset version of the contents. These will only be typeset again if you change the buffer contents (or if you are typesetting with a different version of ConTeXt.) See https://wiki.contextgarden.net/Command/typesetbuffer My biggest book is about 200 pages. It takes 4 minutes to fully typeset on an M1 Mac. (I saw this time after downloading a new ConTeXt version.) This is mostly due to the 100+ complex TikZ diagrams. However, all of those diagrams are buffered, and when I’m working I only typeset the component. A typical chapter typesets in 1.6 seconds if I haven’t changed the diagrams. (I just did one to check.) That’s fast enough for me. Hope that helps, Gavin

I can process TeXBook in almost an instant using PDFTeX which is about 450+ pages but my math book takes around 30 seconds averaging ~40 pages/second.
