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.
