Image uploads filling Heroku log output

Actually, I have another question related to this…
When we save the image file on device with

imageFile.saveInBackground({

it takes too much time (more than a couple of seconds per image) to complete, which seems strange, considering it is only saving it on the same device. Could you think of what the cause of this delay?

We are wondering if it tries to access to the remote parse server (on Heroku in our case) first, and it waits until the response comes back (it should fail because our parse server’s CLP setting does not allow to save files this way), and afterwards, it tries to save it locally on the device. Could this be the reason why it takes such a long time to complete “saveInBackground” on device? If so, could you think of any ways avoid this time lag?

Thanks a lot!!
