[Q] Andrdoid Studio lags topic

I installed Android Studio from the Arch User Repository today and every time I run it my PC slows down. When I first started a new project I had 2 youtube video open in Firefox and my PC stopped responding, had to restart it manually. Second time was a bit better, no forefox, but still it took an eternity to switch tabs.
Is there a way of improwing the performance? Is this a fault of missing softwtware or is my PC just too old [specs: 3 ghz dual core, 2 GB of RAM, HD4350, Manjaro linux with XFCE].
