debug code runs a lot slower than release - Visual Studio Feedback.
According to Android Studio's official system requirements, it takes at minimum 3 GB RAM to run smoothly. Honestly, its a lot and I believe that is the biggest cause of being it too slow all the time. The android developers are always complaining about the speed of Android Studio and how its slow ALL THE TIME.
Method breakpoints will slow down debugger a lot because of the JVM design, they are expensive to evaluate. Remove method breakpoints and consider using the regular line breakpoints. To verify that you don't have any method breakpoints open .
In short, USB Debugging is a way for an Android device to communicate with the Android SDK (Software Developer Kit) over a USB connection. It allows an Android device to receive commands, files, and the like from the PC, and allows the PC to pull crucial information like log files from the Android device.
Start your app without debugging and only if you have reached a point where it gets interesting for debugging, then connect your debugger using DDMS perspective -> device list -> debug process button.
Edited in 2014: Nowadays I would recommend trying the Genymotion Android virtualization. In contrast to the original Android emulator it does not emulate the core of the Android device, but instead runs it as x86 code in a virtualized system. That is typically faster. In addition it brings some features the original emulator simply does not have (like map based GPS position selection).

It usually happens in Emulator, especially when you are reading/writing files, making calls to web-server and/or the size of your .apk file increases (large apk size causes slow installation). The best solution is to use a real device which will speed-up the installation process and enhance the overall performance of your app
