Build on Android Studio is slow forever - android-studio

Question

I upgraded Android Studio to version 2.2.3 recently but since then build time has gone up to more than 5 minutes which is extremely frustrating. I have browsed through similar posts and tried to change configurations but nothing seems to work.
build.gradle

maven { url 'https://maven.fabric.io/public' }

I am an Android newbie; am using Windows 10 PC with 8GB RAM. Any help will be appreciated.

Please check the docs, especially the part about the "studio.vmoptions". With this file you can tell how much RAM can be used to run AS.
Keep in mind to set/use the correct (desktop)-shortcuts... By default a 32-Bit-config shortcut is created, I guess (can't check it right now).
