If it still doesn't work, then check your firewall. It shouldn't give

Well all of a sudden iperf.scottlinux.com works The send and receive

As you can see, I'm getting about half of the 50Mbits/sec for which I
contracted. But this is way better than my actual speed. I ran the same
test with udp packets and got:
When I tested against the same host last night I got around 40Mbps (I
also have 50Mbps), but I'm in Norway, so that doesn't seem so bad. I
tried again right now, and got ~45Mbps.
What do you mean that this is way better than your actual speed? This
_is_ the measured speed to this host :) Do you normally get lower speed
to other hosts?
Your ISP probably doesn't guarantee that you actually get 50Mbps
unless you have a business line, but most likely says "speeds _up to_
50Mbps" or something similar. So that would be normal.
Also try a few online speed tests, like the one at speed.io, and see
what they tell you. Your ISP might also have one.

Now I'm really confused. I thought UDP packets were going through at
full speed and TCP plackets were slow. This data says just the opposite.
Yeah, Reco just explained this to me in a different thread. For UDP you
need to specify the target bandwidth, the default is 1Mbps. Use "-b 0"
to set it to unlimited. For earlier versions it needs to be at the end
of the line, don't know about iperf3. See the man page for details.

Most of my large downloads are from ftp.us.debian.org. Before I go any
further, I probably need to switch to a mirror site and see if the
problem persists. I have been assuming that, since this is debian's main
server, that I shouldn't have a server problem. Assumptions can really
kill you. Thanks for info on iperf3's udp speed. running "iperf3 -c
iperf.scottlinux.com -V -u -b 0" works fine. I'll keep you posted about
changing to a debian mirror. There is one at the Univerisity of
California Berleley that is just up the coast from us.
Thanks again

Well, I'm back
I used iperf3 as follows:
iperf3 -c iperf.scottlinux.com

My local network seems to be working fine (I tried the -R switch as

network.
Seems good.
I am behind a verizon M1424WR rev. I router firewall that has been free

problem or has scottlinux.com shut down their iperf3 server.
Well, it's not shut down, as I just tried it and it works fine here.

Well, it's not shut down, as I just tried it and it works fine here.
Maybe it was down, though, and you should try again?
If it still doesn't work, then check your firewall. It shouldn't give
you any problems, as you are simply trying to establish a connection to

I also tried it with the -R switch with the same result.

If they're ridiculously slow compared to your download speed, then you may find that you're not able to ACK packets quickly enough to sustain a steady 50M download (I can't immediately work out at what sort of level this will happen, but I'm sure there's someone more versed in networking who can tell you). Another consideration is to look at the router's statistics page for line errors. You might find that packets are being retransmitted a lot, which will lower the effective rate of transmission (though, if it's to the point of constraining 50M down to 250K, then there's something wrong with the line). Finally, don't rule out the possibility that your ISP is throttling you. While you may be synced at 50M and may be able to transfer at that for short periods (and thus, the ISP can rightly claim that you have a 50M connection), they could conceivably throttle your connection in the longer term. > -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

HELP- very slow download speeds
I have 4 systems that have squeeze, wheezy and jessie on them. I haven't updated one in a long time. They all suffer from extremely slow downloads. I have a 50M verizon fiber optic line to a M1424WR router / switch. I also have fios and my phone line on the same system. When I start a download, it starts at 50M for the first few seconds and then drops to 500K to 100K range. All 4 system react the same. Two are the same hardware but one is older hardware and one is a dual boot Toshiba laptop. Verizon insists their lines are OK. The have change out the router, the interface unit outside and have bypassed the coax with there own. Everything checks out. I have run their speed checker while downloading. The speed checker shows 50M (about) and the download speed is simultaneously around 250K. Everything is hardwired - no wifi hookups. Further, my NetFlix may hickup once in a while but generally works ok. No problems with our phone service. When this started, I was getting lots of packet loss errors with "ping -f -U " but that has stopped today. The slow downloads still persists I'm at a loss as to what is wrong. Any ideas will be sincerely appreciated. I think Verizon is about to dump me on my head and wash their hands of the whole problem. Thus leaving me with a dialup speed expensive connection.
