I am wondering how you did the benchmark.
I just tried the following on my config.org

cd path/to/OrgMode.jl
push!(LOAD_PATH, pwd())
using OrgMode
orgfile = open("/home/yantar92/Git/emacs-config/config.org")
textorgfile = read(orgfile, String)
parse(Org, textorgfile)

The config.org is about 18k lines, but I did not manage to wait enough
for the parser to return.

Multithread looks promising though.

Also, the tests I mentioned are with my latest commit for
org-element-parse-buffer and on native-compiled Emacs.

Thanks for reminding about this. I have seen it, forgot it, and now
reinvent the idea :D.

Also, it would be great to have a unified test set to verify third-party
parsers and org-element parser.

That's my personal notes file. I can test it for you if you give me the
