App Store upload is really slow and hogging my internet connection
It is apple algorithm to validate first then accept application.
Sometime it uploads in 10-12 minutes sometime takes 30 minutes. It depends on internet speed, server load while uploading...
Developers working outside Apple have to keep patience, No Other way
Best is try to upload with Application loader.
I had the same issue and it was completely fixed upon updating itmstransporter.
cd ~ mv .itmstransporter/ .old_itmstransporter/ "/Applications/Xcode.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter" Please refer to https://forums.developer.apple.com/thread/76803 (look at KumobiusIvan's answer)
