Now I am developing some codes in virtualbox ubuntu machine, and the host machine is win7. When the codes are ready, I put the library to the device using the following command adb push abc.so /data/local/tmp/myabcfolder. However, the speed of transferring data is so slow that the shell almost stops. If I push files of small volumes to the device, it seems fine. Any ideas on how I can put the relatively large library to the device? Thanks.

ps: When transferring the data to the device, it reaches a certain mount of data very quickly（393216）, and then stops as the following picture shows:

  • 4Mb is not that big of a file and it should not take more than couple of seconds to upload it. I would suggest configuring `PCI pass-through` for one of your USB controllers in `virtualbox` settings. You won't be able to use any devices connected to that controller in your host system but it will ensure the best possible USB performance inside the VM. – Alex P. Apr 27 '15 at 20:19
  • @Alex P - can you explain how to set PCI pass-through – Les Feb 23 '17 at 21:59

I finally find the reason: it is because when the Android device is attached, it does not use USB 2.0 protocol. In virtualbox, there is a place to set this option:

But in order to enable USB 2.0, you have to install virtualbox extensions.

Best solution here will be to use shared drive:
Mount your real folder to your VBox and it will be much more faster than copying with adb.
