My recent optimizations have been in the case where the display is
up-to-date (as when the cursor just moves within the window), but
not when the display actually needs to be updated / scrolled.
I have just installed a change that should make line-move-partial
about 3-4 times faster when the display is not up-to-date.
If this still doesn't help, I don't see what else I can do.
