What could I do to make it faster? I'm willing to disable fancy rendering
features if needed, but I'm loosing way too much time with the rendering

Just by chance, are you running linum-mode (line numbers in a small column at the left side of the buffer?
I noticed this does not work well with org-mode. I had a file with a few thousand lines and folding took ages.
Switching the linum-mode off and folding was again instantly.
