I usually just use profiler-start/open buffer/profiler-report. However,
there is also https://github.com/Lindydancer/font-lock-profiler for more
fine-grained benchmark. Also, you may instrument org-activate-links with
elp.el (built-in).

I am currently looking into somewhat orthogonal approach. Instead of
tweaking individual regexps (there were similar issues with priority
regexp in the past), I am trying to use custom
font-lock-fontify-region-function. Once we avoid fontifying folded text,
startup time drops several times at least. I can see the difference
immediately. It comes at the cost though - the behaviour of some Org API
functions changes. They will not always return fontified text. AFAIK, at
least helm-org and helm-org-ql do reply on such fontification.

They are generated by aggressive-indent. Since org files mix indentation
styles I keep getting those whitespace changes in my patches. Forgot to
remove this time. Should I?

Best,
