There is no need to parse all *.txt file

It's enough to parse tags file, which is simpler and faster

Which tags file are you talking about? If you're referring to the code in help_tags_extractor then it parses the txt files and compiles the tags into the database. Those files are parsed and the tags are compiled into a database so it doesn't affect the runtime at all.

[GoldsteinE]

Yeah, I'm about tags extractor.
Just saying there's a simpler way to parse tags — from tags file instead of txt file.
/usr/share/vim/vim<version>/doc/tags for Vim.
