Hi
I was searching for a new stack (prefered based on php) for one of our services which would be develop from scratch. our development team are happy with php (laravel) and a bit familar with golang.
Looking for your experiences on these kinda new technologies and do you have any application on production with these stacks ? | 
As far as I know, Laravel by default with its caching mechanism can handle a lot of traffic; if however you are going to deal with millions of requests per second, then indeed you will need a faster backend support, which in this case either swoole or the other two aforementioned projects you asked in the title will work flawlessly.
