[Message part 1 (text/plain, inline)]

Hey,

Nope, sorry. Doesn't seem to help.  What I did:
started emacs with

#emacs -Q lorem-ipsum

emacs opens in fundamental mode with the file (attached)

# M-x eval-expression
# (setq inhibit-compacting-font-caches t)
# buffer-face-set
# variable-pitch

Slow as before. Attaching the profiler logs
