The Pull Request ruby/rdoc#551 has many changes for frozen string literal because RDoc expected that all strings are non-frozen. The log "before" that has frozen_string_literal: false is faster than the log "after-false" that has frozen_string_literal: false. Only the implementation changes increase document generation time by 2.6%. But in the case of the same implementation, the log "after" is faster than the log "after-false". The addition frozen_string_literal: true reduces document generation time by 1.6%. Finally, the implementation changes and frozen_string_literal: true increases document generation time by 0.9%.
