This graph has 'inv' and 'tx' sent messages for comparison. http://i.imgur.com/keyitsS.png Now, these are just message volume and not actual resource usage, but I have a feeling that 'getaddr' requests are not resource intensive since it shouldn't be reading from disk. I could look into adding timing metrics around these requests if you think it could be useful. - - Jameson On 07/31/2014 06:37 AM, Mike Hearn wrote: >> >> I suspect it is something that is going to have to be dealt with in the >> future (I just don't know how yet). >> > > The web has managed to survive despite constant fast crawls being the norm > for the past 10 years or so.
