In what version of Emacs? I think it was slow in 26.1, but wa ssped
up significantly since then.
If you are using emacs-26 or the master branch from Git, and it is
still slow, can you show an example where it's slow, and tell how much
time it took?

AFAIR, the speed of replace-buffer-contents doesn't depend at all on
whether markers are preserved or not, so I don't think this will
matter.
