Question Only: How long should upload take?

[SteveKennedy]

This is not a bug. Just curious if I should expect a 5.75mb AAB to upload over 500mbs connection. Does this 15 minutes seem reasonable? Is there a way to ASYNC the upload while progressing the build?

It depends on the runner & Google's servers. I've seen anywhere between 15 seconds and timeout so 😛
Follow-up question: How do you know how fast your runners internet connection is?

Nope
