Mamp localhost resolving very slowly

When I make local changes to my PHP / WordPress website, the localhost does not seem to update for 20-30 minutes.

I'm on Mac OSX 10.8.4 and using MAMP Pro. I have two sites that I have created separate host entries for, let's call them mysite1.dev and mysite2.dev.

Here is my MAMP Server configuration:

Apache: 80
MySQL: 3306
SSL: 443

I saw this article ( How can I eliminate slow resolving/loading of localhost/virtualhost (a 2-3 second lag) on Mac OS X Lion? ) on the Bonjour conflicts and edited my /private/etc/hosts file with the suggestions in this article:

1. I changed the host names from mysite1.localhost to mysite.dev because it sounds like the conflict is with .local names - DID NOT WORK
   
   

2. I updated the Hosts file to have separate ::1 addresses - DID NOT WORK:

   ::1 <tab> mysite1.dev
   ::1 <tab> mysite2.dev
   

3. I tried putting all of my host entries onto one line - also didn't work:

   127.0.0.1 localhost mysite1.dev mysite2.dev
   ::1 localhost
   fe80::1%lo0 localhost
   

It seems like MAMP Pro overwrites the hosts file any time I restart the server.

I would be SUPER grateful for any help you can offer.

Change MAMP cache to OPcache. It worked for me

I had the same problem and found the solution on this post: MAMP time between seeing live changes

The instructions, which I followed:

The solution is uncommenting lines in the php.ini file, which can be found in

/{MAMP Directory}/bin/php/php5.5.3/conf/php.ini

Comment out Opcache:

[OPcache]
;zend_extension="/Applications/MAMP/bin/php/php5.5.3/lib/php/extensions/no-debug-non-zts-20121212/opcache.so"
;  opcache.memory_consumption=128
;  opcache.interned_strings_buffer=8
;  opcache.max_accelerated_files=4000
;  opcache.revalidate_freq=60
;  opcache.fast_shutdown=1
;  opcache.enable_cli=1

Documentation ( yes it started in 5.5 ):

http://www.php.net/manual/en/intro.opcache.php

I had similar problems running php 5.5.3. After I changed back to 5.4.19 it worked.

You can change the version in the MAMP GUI. You might have to rename your 5.5.3 folder to 5.5.X for 5.4.19 to show up in the GUI. The php folders are placed at: Applications/MAMP/bin/php
