Fiber is built on FastHTTP. If you know Go top "frameworks" performance characteristics then you would know that you are actually comparing HTTP implementations - ala whether framework is based on FastHTTP or Go standard library HTTP implementation. Framework own % there is for the top 5 almost non-existent.
I would assume this is same case where - what ever Socketify is based on (pythons transport layer), is compared to FastHTTP. and mention of Fiber is click-bate.
socketify is based on uWebSockets (C++)
uWebSockets is comparad to FastHTTP and socketify adds a lot of features on top.
