The applicatios works very slow when is en CI_ENVERONMENT=develop

Have you set a correct app.baseURL="http://localhost:8080/" ? As it will fail to load the debug bar, most likely creating that lag.

Thanks, the problem was that
I had writen "http://http://localhost:8080/"

I had reviewed all the code many times but i had not realized this.

Thank you very much for the help.
