It's an output from a code assistance tool listing all classes in our 
internal application, including libraries. I probably shouldn't 
distribute it.

But it's basically a long list of entries like:

[["Gem::Licenses",null,"suggestions",[["req","license"]],"/home/dgutov/.rbenv/versions/2.6.1/lib/ruby/2.6.0/rubygems/util/licenses.rb",429],["Gem::Licenses",null,"match?",[["req","license"]],"/home/dgutov/.rbenv/versions/2.6.1/lib/ruby/2.6.0/rubygems/util/licenses.rb",425],["URI::Generic",null,"use_proxy?",[["req","hostname"],["req","addr"],["req","port"],["req","no_proxy"]],"/home/dgutov/.rbenv/versions/2.6.1/lib/ruby/2.6.0/uri/generic.rb",1545],["URI::Generic",null,"default_port",[],"/home/dgutov/.rbenv/versions/2.6.1/lib/ruby/2.6.0/uri/generic.rb",33],["URI::Generic",null,"component",[],"/home/dgutov/.rbenv/versions/2.6.1/lib/ruby/2.6.0/uri/generic.rb",58], 
...

If you think it would help, I can anonymize it and send the result, but 
large.json posted by Ivan here previously shows the same performance 
characteristics, I think.
