Title: Bitcoin Core 0.9.2.1, 450 MB IN, 3 GB OUT, normal?
Post by: tr0ubles0me on August 15, 2014, 01:37:05 AM
The network bandwidth tab in the console shows these numbers for a period of 18 hours: IN 350 MB, OUT 3 GB. Also, a month ago it synced 7 days of data for about 30 min, and recently it takes about 1-1.5 hours to do the same. I run it about once a week, because I don't want it to accumulate lots of unsynced data.

What is the client uploading so much? I thought the download should be more.

Any ideas?

It's likely uploading transaction queue and blockchain to multiple peers (8+) while you only receive one copy. Running a sync'd client is roughly like seeding a .torrent. You can force Core/QT specifically to reduce how much data it's sharing with an application-level throttling program like NetLimiter -- it functions fine throttled to ~3kb/s up, ~5kb/s down, keeping in mind you wouldn't be contributing anything significant to the network that way.

You don't mention if you have port 8333 open.

"In" for that time frame sounds about right. "Out" depends on your peers as Kluge mentioned.
