It’s probably not slow PHP, just slow routing. Open terminal and type in hostname to get your hostname (example: myhostname.local). Then run sudo nano /etc/hosts and update it as follows:
::1 localhost myhostname.local 127.0.0.1 localhost myhostname.local
If you are using a virtualhost name (such as vhost.local), you can update it as follows:
::1 vhost.local myhostname.local 127.0.0.1 vhost.local myhostname.local
