The team has finished some further work on this, and is reporting the performance should be back to about previous levels. There is certainly still room left for improvement, and the team has an open feature request to improve performance in general, but I don't have a timeline for if/when further improvements would be implemented.

I am having the same trouble of extemely slow upload speeds, no matter I set chunk size to 5 MB or 100 MB. It's only 191 MB file I am uploading. Please help, there is no official iOS sample code in Objective C or Swift though. Progress callbacks always arrive every 32 KB.

    Also, many a times upload simply hangs without throwing any error. Setting large block size to 100 MB causes such problems more often.
