Considering one of the project goals at the top of the readme is "Don't be obnoxiously slow" obviously not - it doesn't claim to be fast at all.

the first line of text in the web page is literally "Blazingly-Fast Lua runtime"

You responded to a post about https://github.com/kyren/piccolo, not to the top level post about an entirely different project.

The word "blazingly" exists nowhere on piccolo's github page according to ctrl-f.
