Android Studio 2.2: gradle sync very slow
<p>i find that AS 2.2 preview 3 and 4 are very slow when doing gradle sync.</p>

<p>i have <code>classpath 'com.android.tools.build:gradle:2.1.2'</code> and <code>distributionUrl=https://services.gradle.org/distributions/gradle-2.14-all.zip</code>.</p>

<p>the gradle sync always takes more than 1 hour. what's more, when the sync finished and i restart AS so that sync is started again, the sync is slow again: the sync is slow every time i start AS...</p>

<p>my PC has: i7-6700, 16G RAM, 512G SSD.</p>

<p>when i use AS 2.1.1 for the same project, the gradle sync is very fast, about 1-3 minutes.</p>

<p>it is a bug, or because my project has 12 necessary modules, or is there some workaround?</p>
