IntelliJ IDEA 13 extremely slow compilation

After setting up IntelliJ IDEA 13 with java 8 sdk for the first time i've noticed that the compilation process was extremely slow. Printing out a simple 'Hello world!' took exactly 3 minutes and 38 seconds. I have no idea what is causing it to be so slow. When i run the code in Netbeans for example it compiles and runs instantly. I've done some research and sought for solutions but other than removing plugins i wasn't able to find anything. Does anyone here have any idea what might cause this problem?

You have to disable every unwanted plugins that you have.

Go to Preferences > Plugins > Installed and then you can check all your installed plugins that you have. You can deselect Kotlin if you are not thinking to use it (or code with that language) and other stuff that you will not use. Apply it and test it. See https://www.youtube.com/watch?v=-IVAGtnRkzg

It worked for me.

I had the same issue. Upgrade your machine, you will definitely need one with an 8GB RAM. Also, reinstall IntelliJ with only the components that you need, this will increase the startup time of IntelliJ. Make sure you do not have any memory intensive program running along with IntelliJ in your current system. These things helped me.
