Hey @joeldrapper!

There is a drop-in replacement gem Nokolexbor for Nokogiri. Which claims to be 5.2x faster at parsing HTML and up to 997x faster at CSS selectors than Nokogiri.

What do you think about creating an extra gem phlex-testing-nokolexbor in order to utilize that speed? Is it reasonable?

From the Nokolexbor's Readme: It's a performance-focused HTML5 parser for Ruby based on Lexbor.
It supports both CSS selectors and XPath. Nokolexbor's API is designed to be 1:1 compatible as much as possible with Nokogiri's API.
