wrap your require statement with an ‘if defined?()` check.
Rubygems is VERY slow to require gems even if they’ve already been loaded. To work around this

def on_send(node) 

def on_send(node)
  require?(node) do |r|
    next if node.parent && node.parent.conditional? # catch both if and unless
    next unless REQUIRE_TO_CLASS[r]
    add_offense(node.loc.expression, message: MSG, severity: :refactor) do |corrector|
      corrector.replace(node.loc.expression, "#{node.source} unless defined?(#{REQUIRE_TO_CLASS[r]})")
    end
  end
end
