Improve Android Emulator Performance on Windows 7 x64

Question

Possible Duplicate:
Slow Android emulator

I'm running on Eclipse Helios on Windows 7 x64. I have a Core 2 Duo 2.0 Ghz with 4.0 GB which I think should be enough, since I've never have any performance problems with developing tools.

When I run my first app on the Android Emulator (both 2.3.3 and 3.0) it took at least 5 minutes to load the OS and at first it didn't even run the HelloAndroid app. Even when I managed to run the application, the performance was unbareable.

The strange things is that is not a OS performance issue. This is the CPU and Memory status while executing:

CPUPerformanceWhileRunning

I've tryed various things to improve the performance, but no major improvement is shown. I think I'm missing something.

Things I have tryed:

On AVD Manager

Device RAM size to 512.
Resolution to 640 x 480.
Snapshot enabled.

On Project preferences\Android

\Launch\ -cpu-delay 0 -no-boot-anim -cache ./cache -avd Android3

Things I can't tryed: - Deploying on a device (don't have any).

By the way, I've had the same problem on a MAC Mini 2.66 Ghz 2 GB but these settings made the difference.

Anyone can give any tips to improve this lame performance?.

Yeah, it does take some time to load up the simulator. Just don't close it afterwards! You can still build apps while it's open! — Matthew, Apr 07 '11 at 03:55
Try upping the RAM to 1024, but I do most of my debugging on devices for this reason. — Joseph Earl, Apr 09 '11 at 20:45
The problem is that even when the emulator is loaded (when it does), it runs extremely slow. — mikywan, Apr 09 '11 at 20:50

Unfortunately, you are not alone on this.

There doesn't seem to be a good solution, but a few tips:

Start the AVD directly, not through the IDE
Leave the AVD running instead of closing/restarting when you change code
Debug on a real device. Yes, you lose testing on multiple versions and resolutions, but for many of us, it's the only bearable solution.

Hope this helps a bit...

I had the same issue, the emulator would freeze at "android_". I fixed it by changing the compatibility mode on emulator.exe to "Windows 7". Now it's always slow, but it's running.

Open taskmanager and right click on emlulator-arm.exe (*32), klick processor affinity (affiniteit instellen) and select (if you want ofcource) or just select te cores you want to use. Increases the performance a lot for me (with eight threads available)!

My performance issue was mainly caused by the resolution of the Emulator. I set the resolution to one of the default values of the emulator resolution and it's working much better. I wouldn't say it works as good as the iPhone simulator, but I can work with.
