</tt>This is from some stats for the CW Skimmer that I collected
in DXSpider over this weekend (so far). The "spots out" figure is
the number of spots that I have left after I have done my
de-duping thing. A user will get only that number if they have
asked for all spots and have no filters. So, in principle, each
user could get the full "spots out" number. Most people will
likely have some kind of by_zone filter on. But I can't give any
likely numbers, this time, because the number DXSpider users
receiving were not large enough to get a meaningful feel of how
well it is likely to cope, but there does not seem to be any
obvious difference in CPU between no RBN and RBN+2/3 users, I am
reasonably confident that it will cope. <br>
<br>
But I was curious as to how many I could stuff through -
unoptimised. So I did some benchmarking.<br>
<br>
So analysing today's debug file and extracting just the CW
Skimmer's RBN spots with 100 simulated users being sent the
curated spots gives:<br>
<br>
***<br>
*** Totals: raw = 1882260, candidates = 539920, delivered = 76926,
percentage of raw delivered = 4.087%<br>
***<br>
*** Total elapsed time = 90.18 secs for RBN activity of any kind,
each delivery to 100 users = 0.001172 secs or 853 / sec<br>
***<br>
<br>
It's a bit optimistic but not by too much. It should cope with 42
/ sec at the peak. But I *still* think that it is an egregious
waste of bandwidth just to get 4% "useful" (contest) data. I am
also musing to myself: what happens if most of the DXSpider nodes
start sucking data from the RBN? I am guessing that they will be
running out of NIC bandwidth with another 150 or so DXSpider nodes
(out of ~250 odd). At my estimate of 77 bytes (not including TCP
overhead) that's 4+GB (that's B, not b) altogether with 200 other
users. That's 5 10Gb NICs bonded together into a router, in turn
connected to quite a fast pipe to the Internet, even by today's
standards :-) I'd love to see the AWS bill.<br>
<br>
I enclose the csv for your Excel manipulating pleasure (or some
other competent spreadsheet program [amongst which LibreOffice
does NOT figure]).<br>

Each spot from the RBN is 300 bytes. Busy times can see over 4 million incoming spots per day. 4,000,000 x 300 bytes in. Then add the outgoing data.

Hi Dirk.
Yes, I think that I will upgrade to mojo branch no matter what.
I am still having doubts about the RBN thing though. As I wrote earlier I am on a limited plan,
which means I pay a very low price per month. I am only allowed 1 TB of data a month.
I was logged on the the RBN network port 7000, and it said that the average at that time was
17000 spots an hour. And that is probably at the low end when contests are there. This is a
normal sunday evening without any contests (that I am aware of).
17000 spots an hour, I count a spot as 80 bytes, means that just with that I will be using
around 1 TB of data in 30 days. The next plan at my provider is a lot more money, so guess I
am bowing out on the RBN stuff. Unless my calculations are way off.
I guess in busy contest weekends the number can increase to 50000 spots an hour or more.

Thanks for the info. I will not touch it now since there is the contest this weekend, and I will
not be home to monitor what happens.
Will this new RBN data increase the bw used by the node significantly? If we are talking 100
spots a second, like someone mentioned, I am not sure it is for me, since I have limited bw
useage.

That is the $64,000 question. If you stick to CW spots, so far, I have
seen about ~10/sec during the last big contest. We will see what this
weekend brings for a more definite answer. I would be quite surprised to
see 100 spots/sec or 8200 bytes/sec. But remember, the most you are
likely see coming out is ~820 bytes / sec / RBN Spot user and. even on
the last big CW contest the actual "curated" output was 1 or 2 / sec,
but not consistently. 30000 incoming spots / hour would be whittled down
to about 3000/hour or about 8 every 10 seconds.
I am waiting with bated breath how WA9PIE-2 copes with 1000+ users.
Human spots is no problem at all, it trundles along at about 2-7% CPU on
a big contest. But it is unlikely that (anything like) that many of
them will using the RBN feed - at least this weekend. But we will see.
1000 * 820 is how many bytes/sec again...?
But I would strongly recommend that you upgrade, just for the improved
speed and reduced power consumption. Whether you connect to the RBN is a
separate issue. The 'mojo' branch is where it is all at. The 'master'
branch is now just in care and maintenance. All new features will go
into the 'mojo' branch (there is a clue as to what it is in UPGRADE.mojo),
