Hello

Since the april 10 "crisis" Smiley  I have noted that bitcoin-qt wallet is using a lot of outgoing bandwidth, almost 90% of my capacity

I have between 20 and 60 connections to the bitcoin network, any idea if this is normal?

If I shutdown bitcoin-qt the traffic stops.

is there is any way to limit the outgoing bandwidth that it uses? I have no problem helping bitcoin network but when I am unable to work because of low remaining bandwidth is another matter Smiley

thanks
Indkt.

Even in the event that an attacker gains more than 50% of the network's computational power, only transactions sent by the attacker could be reversed or double-spent. The network would not be destroyed.

this has already been discussed.

tl;dr summary:
it's normal, there's no built-in way of controlling it. partial solution involves setting the connection count to something low.

It is pitch black. You are likely to be eaten by a grue.

THank you for answer

Do you remember where it was discussed?, because I can't find it.

The connection count, where can I set it?, there are not configuration files for the wallet (at least I cannot find any), the other option is to disable the port forward, that should decrease the amount of people connecting to me, but this is harmful to the comunity and I prefer not to do that.

thanks

Someone's gotta distribute that fucking blockchain!

Maxconnections and disabling port forwarding is a pretty crude solution. If you're trying to use the Internet outside of hosting the blockchain, you could download a program like NetLimiter and set bandwidth caps either on the program or on the specific peers. Unfortunately, though, Bitcoin itself does not currently have this functionality.

Sounds normal. I usually hover between 50 and 60 connections, but I limit my entire network outgoing bandwidth in my router (my ipcop linux box, actually) to 500kbps. I leave my machine on 24x7.
