What does "0.18417s from unicorn-785bf9c5d8-mgr5g" mean?

As mentioned in this old (2009) blog post, this refers to Unicorn, an an HTTP server for Ruby, similar to Mongrel or Thin.
So this measures the page rendition time.
This is illustrated during their 2017 move to Kubernetes
Before this move, our main Ruby on Rails application (we call it github/github) was configured a lot like it was eight years ago: Unicorn processes managed by a Ruby process manager called God running on Puppet-managed servers
I am not sure about the significance of it and probably someone from github could only be able to answer it.
But in general, that is the title attribute in span tag.
