Bitcoin Core 0.12.0 added many bandwidth (e.g., maxuploadtarget) and rate limiting (e.g., with maxmempool) features.

I have maxuploadtarget set to 0 (default; unlimited), yet I used to get several gigabytes of traffic each day. Now I only get a few hundred. Why?

What must I do to make Bitcoin core maximize my bandwidth?

The new option is called maxuploadtarget. It joins maxconnections and listen in the list of things that can be used to control the bandwidth and resource usage of your Bitcoin client. maxuploadtarget controls the bandwidth used in a much more precise way than was previously possible without external tools.

maxuploadtarget is off by default. You don't need to do anything. More documentation is available here.

  • Yes, but I used to have several gigabytes of traffic per day. Now I only get a few hundred, even with maxuploadtarget=0 (unlimited). Why?

    Several gigabytes per day sounds like someone was downloading the blockchain from you. Perhaps they're done? Mar 4, 2016 at 16:52
