What are the bandwidth requirements of a mining rig?
How much bandwidth consumption can I expect per 900 Mhash/s rig (for instance) for both pooled and solo scenarios? I'm looking for a ballpark number for the on going requirements, after the initial blockchain download.

Bitcoin Core uploads much more than it downloads
Since Bitcoin is a peer-to-peer network of mostly identical clients, I would expect each node to upload about as much as it downloads. So I was surprised to see that my Bitcoin Core node has (since last startup) downloaded 1 GB of data but sent 47…

Quantity of traffic on test network
I want to begin experimenting with bitcoin. I notice the estimated upload traffic for the real bitcoin network is around 200 GB per month. That's too much for an experiment. How much traffic per month could I expect for a node on the test network?

What hardware requirements does a SPV client have?
I read about SPVs here that:
[A SPV] client downloads a complete copy of the headers for all blocks in

How much internet traffic does a 3.5GH/sec pooled miner use?
The question is clear I think. I used 3.5GH/s because that's what the upcoming ButterflyLabs Jalapeno will run. Assume it's mining for an average mining pool with 3.5GH/s (only bitcoins).
I'm interested in maintaining one on a spot where I can get…
