Build on Android Studio is slow forever

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

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        jcenter()
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
        classpath 'com.android.tools.build:gradle:2.1.3'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.3"
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'

    }

    defaultConfig {

                                onesignal_google_project_number: "XYZ"]
    }

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

I have experienced performance issues in the past which were only solved by a fresh re-install of Android Studio. However, I've recently updated to version 2.2.3 as well and performance is decent. But, I also switched gradle to version 2.2.3. `classpath 'com.android.tools.build:gradle:2.2.3'` — yogur, Dec 26 '16 at 17:09
I have already tried compiling with the gradle plugin version 2.2.3 but unfortunately the problem persisted — Ranjan, Dec 26 '16 at 18:27
Did you check my answer here? http://stackoverflow.com/a/31633775/3145960 — Reaz Murshed, Jan 02 '17 at 07:26
Your suggestion has helped. I have been able to reduce build time from 8 minutes to less than 2 minutes. Moreover, I am new to Android therefore wasn't aware that "Clean" is not required every time I run the application. "Clean" was removing all dex outputs which was taking a very long time to recreate.

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).
