title: Emulator uses too much ram
body: <p>I've just installed the Android SDK and create my AVD, but I've got a problem.
  I'm on a Windows 7 x64, with an Intel i5 and 4GB RAM, so the emulator should run well.</p>
  
  <p>But when I start it, on the windows task manager, I can see that it use more than 1GB of RAM!
  Is it possible?!</p>
  
  <p>I tried to use snapshot, tried to set the device ram size to 1024 and tried to remove the SD emulation, as adviced in other question like this, but nothing changes.</p>
  
  <p>Should I try to remove some SDK? Because I've installed a lot of them, for try to launch app in some different devices... but if them are going to slow me down, I'll just keep the 2.2 and 3.0 and no other else...
  Or maybe I shoud try to run in a x86 system?</p>
  
  <p>Thanks!</p>
