About a week ago I said I would set up an unstable node that was deliberately
firewalled to see if it could be of any use to the network. Here are the
results.
First I was running unstable at the current version of it. Then when 5031 came
out I switched to that. I currently have over 300 connections and just over
100 transmitting data. The number of connections has remained fairly constant
except after I shut it down to upgrade it. (It does not supprise me that I
have so many connections transmitting. As there is some external packet
filtering software which is slowing down individual connections, but Freenet
overall is running with effectively unlimited bandwidth.)
In any event my node is constantly about 1 stdiv above the network average in
terms of load, (current 40K QPH) and about a .25 acceptance rate, which from
what I gather, now a days is above average. And my routing time is typically
between 10 and 20 ms.
Most notably my node has been able to sustain connections for long periods of
time. Some of them for nearly the entire uptime of my node, and some with
several thousand messages transmitted.
Memory useage is excellent. I am seeing extended periods of under 30MB of
useage. Although I had seen a strange behavior on some previous versions. It
would load up and function and I could brouse Freenet, come back and check my
memory useage and it would be something like 40MB. Then it would VERY SLOWLY
continue to climb ever higher until it got near the limit then the garbage
collector would activate and that would take it down about 20MB and then that
process would repeat. I have not yet seen this on 5031.
One other weird thing is that I see a lot of these messages in the log:
Took 1672 seconds to send [EMAIL PROTECTED]:freenet.Message:
QueryRejected @null @ dbac31a18d9f50: htl=1, reason=Node
overloaded:QueryRejected{Close=false,Sustain=false,DataLength=0,{HopsToLive=1,Reason=Node

73b4 c208 bf88 57fa 9d09 055d f426 7c5d)): outbound attempts=22:4/26
I don't know what causes that, but overall I would say it seems to be fairly
healthy and as far as I can tell contributing to the network. This has not
been possible to my knowledge until quite recently. So I would say, that as
long as there is no great harm in doing this, that maybe we should stop
recomending users that are behind NATs/Firewalls that are out of their
control to be transient. This is also a good sign in that some of the more
elaborate measures, such as shadow nodes may be unnecessary. Maybe we should
just have a firewalled flag so other nodes know not to bother to contact you,
and let that be the end of it.
