Working on 1600pg history book with large text and photos in Indic language (malayalam)

So i started working on a history book in malayalam language. It consists of 3 volumes, the first book has 10 chapters and i've splitted into 10 files and used the book feature in indesign. Each chapter is about is about 40-50 pages with 2 column, justified text, and text wrap.

My problem is it lags so much even in fast preview. It is frustrating to work and takes up alot of time. And i've attached my justification settings as well for reference. However, i've been finicking with justification setttings, if i don't use glyph scaling at all, it speeds up by alot.

My question, how will i use this feature without affecting my performance, the glyph scaling plays a good chunk of my workflow. And i can't just turn it off and on everytime.
