Taking 20 mins to send a 10MB file

[Joseph Liu]

I've tried two methods of sending a 10MB file:

1. Sending over a stream byte by byte

2. Sending as a single message

However, the result is still the same; it takes 20 mins or so to send over the payload in a single gRPC call.

What can I do to make this faster?

I have done something similar. I am sending the data with 1.9MB per message using a stream. For now, I am limited by the underlying storage system that takes sometime to write the data (using gRPC/Java/Google Cloud). I am transferring up to 140GB this way.

I can achieve 20-30 MB/s.

If you give more details, it might help to understand why it is slow for you (running locally or not, where are you writing the data you receive...)
