I'm currently using Calibre on a MacBook Pro 2018 with an i5 processor, 16GB of RAM, and 1TB of storage. However, every time I open an Epub book, it takes about 20-30 seconds to fully load.

Apparently my external monitor (plugged via USB-C) was responsible for the slow down. Unplugging the external monitor (DELL S2722QC) will decrease startup time to 3 seconds!

Plugging in the external monitor and decreasing the resolution of it will decrease the load time to 7 seconds (down from 30s). Still not as fast as on my Macbook screen (3 seconds).

I am guessing that the viewer reads the resolution of the screen and calculates the page size for every page to be opened?

Anyone can point me to a solution?

Thank you very much!
