Notice the memory usage in the title bar and/or status bar. When GIMP is using all of your memory, everything will be very very slow. (1) Make sure the "tile cache size" is set to at least half of your physical RAM in Edit->Preferences. You may need to experiment as you didn't mention operating system or how much memry you have or whether 32 or 64 bit. (2) there were some speedups - get 2.10.14, not 10.4, and see if that helps? i routinely work with large images but not with 35 layers. Sometimes 40,000 pixels on a side. slave liam -- Liam Quin - web slave for https://www.fromoldbooks.org/ with fabulous vintage art and fascinating texts to read.
