My Aquia Dev Desktop is insanely slow. What could be the problem? I'm running Drupal 7 with the latest version of Aquia Dev Desktop and the site is REALLY slow on local host. I mean something like one minute to load a node  to edit it, and three minutes to load the modules page.

I tried the Boost module, and I have all the performance settings maxed out.   What could the problem be (a port, the PHP version, too many installs)? I have about seven sites in there.

The site on the live server (in the USA) is faster and I'm connecting from Thailand; that is twice as fast as localhost.
I experienced the same thing when I tried using the Acquia Dev Desktop. 

I now use c9.io (clould 9) and do all my development in the cloud :) 

Here is a nice overview video of the IDE.
