CI 4.0 Micro-framework?

Lumen is good but its just micro whereas Codeigniter is already a full-stack yet faster. Enabling the right library at the right time  makes the most out of codeiginter's speed and power. Here is one benchmark I could find, https://github.com/kenjis/php-framework-benchmark and yet it shows codeigniter is faster even closer to a "micro framework" slim. As what everybody said, the initial lumen installation is just static without controller view hence its fast.
