CI 4.0 suggestion forum?

Slow and bloated? Haha! That's a good one! 

It is actually.  I'll lazily link to an article:

I had a requirement for tens of millions of requests a day with a page that could not be cached by varnish.  Codeigniter was very slow.  After I took slim framework and forked it to my requirements.  It flew under the load.

I know this is probably hard to read for some.  

But the right tools for the right job!
