Deployment performance

Any suggestions on how I can increase the performance of deployment to device? Right now I'm looking at about 40 seconds wait before the application starts up on the device.

1>Packaging application..
1>Microsoft (R) Build Engine version 4.0.30319.33440
1>[Microsoft .NET Framework, version 4.0.30319.34003]
1>Copyright (C) Microsoft Corporation. All rights reserved.
1>
1>Build started 12/5/2013 11:24:02 AM.

....

========== Deploy: 1 succeeded, 0 failed, 0 skipped ==========

Build Summary
-------------

Total build time: 00:21.297

========== Build: 0 succeeded or up-to-date, 0 failed, 10 skipped, Completed at 12/5/2013 11:24:40 AM ==========

As you can see build started at 11:24:02 and ended 11:24:40, 38 seconds later.

Thanks
