I have been testing the phpFox iOS app linked to the phpFox demo site and well as my own phpFox site. I have noticed that it takes between 30 seconds and 60 seconds to upload a single image. When I try upload the same image via the Facebook iOS app, it uploads in around 3 seconds!
From what I understand, this performance difference is due to phpFox uploading the full size image whereas Facebook resizes the image before uploading.
In my opinion, this is a huge user experience issue. People do not want to twiddle their thumbs for a minute waiting for images to upload!
What do you think?
