How can I eliminate slow resolving/loading of localhost/virtualhost (a 2-3 second lag) on Mac OS X Lion?
dns, localhost, macos, osx-lion, virtualhost
Solution
I had the exact same problem and it was driving me crazy!
Put all your hosts file entries for localhost into one line like so:
127.0.0.1 localhost myproject.dev myotherproject.dev
::1 localhost
fe80::1%lo0 localhost
Worked like a charm for me. Seems like a bug in Lion.
Problem
Since setting up my development environments on Mac OS X Lion (brand new macbook air purchased in January 2012), I have noticed that resolving to a virtual host is very slow (around 3 seconds) the first time but after that is fast as long as I continue loading it regularly. If I leave it untouched for a couple of minutes and then reload again, the first reload is (again) painfully slow; seems like something is being cached. As can be seen below I am not using the .local TLD. My setup: Apache 2 - MySQL - PHP installed and enabled - added a couple of virtual hosts one of which I created for localhost My /etc/hosts: ``` 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost 127.0.0.1 myproject.dev ::1 myproject.dev fe80::1%lo0 myproject.dev ``` My virtual host set-up in username.conf: ``` NameVirtualHost *:80 <Directory "/Users/myusername/Sites/"> Options Indexes MultiViews AllowOverride None Order allow,deny Allow from all </Directory> <VirtualHost *:80> ServerName localhost DocumentRoot /Users/myusername/Dropbox/dev_envs/ </VirtualHost> <VirtualHost *:80> ServerName myproject.dev DocumentRoot /Users/myusername/Dropbox/dev_envs/myprojectname </VirtualHost> ```
