this is mostly true for copper based systems due to loss of signal integrity during transitional up-amp of signal. as the signal does get slightly distorted and thus interpretation of destination and content takes longer.

No, it is true for all types of mediums (when TCP is used). The formula I am talking about is just as true for ADSL as it is fiber or satellite. It has nothing to do with the processing needed for error correction. It is based on the fact that your computer has to acknowledge receiving the frame.

Distance based speed loss is not so much a factor for fiberoptics. However the main reason for loss of speed over distance is that the ISPs own different subsea cables. and depending on your ISP, you may get throttled at the final destination.

I had this issue with servers in germany. Some danish ISP holder wasnt too happy with my ISP for a while, so the signal which goes through subsea cables were throttled as the signal was down-prioritized on its way to germany and back.

Some months later, the ISPs stopped bitching at eachother, resulting in speed and latency returning to old values.

 

I do not know WHO owns or have the control over the subsea cables, but i do know that dutch ISPs got on the wrong side of murican ISPs during the original TBP trails/hunt and that they got throttled by US ISPs. But i thought this was no longer the case.

That might very well have happened, but the fact of the matter is that even without any throttling, your data throughput will be lower when having it processed over many, many network units (if you use TCP, which this does).

 

If this only has a server in the US then you CAN NOT use this to determine if you are being throttled or not. You will get lower speeds connecting to the US from for example Sweden regardless of your ISP throttling you or not.

Office ISP is Time warner cable. Ookla consistently gets 350mbps. Fast.com gets 290~300 and once test gave me 120mbps and another having 260.

Comcast for a fact throttles no matter how much they deny it. I can watch videos on Xfinity TV w/o any buffer but the moment I switched to YT or Netflix = buffer and low quality. I had the 100 mbs high speed plan.

 

Even better - I told them I was canceling service and that May would be the last month and my internet just up and went to shit. MONTHS of zero issues and the day after I call to cancel both my 2.4/5ghz wifi signals are dropping in and out and even my hard wire connection from my computer is capping at 30 mbps....I called and they tell me everything is fine on there end.

>Pays ridiculous price for unlimited data @25 down and 2.5 up.

>gets 10 down and 2.5 up.

 

Fast.com and speedtest show the same result; that my internet is shit.

Quick thoughts on system: I7 is extremely quick and I'm glad I spent the extra for hyper-threading. I regret my decision to get the GTX 970, it has horrible coil whine. There isn't any excuse for this terrible whine I and others are having. I HIGHLY recommend a 144hz monitor. Future Improvements/upgrades: Rubber fan mounts, basic speakers, more ram (for a total of 16gb), replace GPU.

144hz is love. 144hz is life. I like to submit unfinished posts then do about 20 edits. I like the Night Theme too.

Spain, Vodafone. i guess you don't need more  throughput than this to run anything

 

fast.com:                  46         Mbps

 

Speedtest.net:      122.08    Mbps

That's odd, I'm using vodafone as well in Spain, Valencia. Paying for 50, 52.4 on speedtest and 53 on fast. O.o

About two years ago when Comcast and Netflix were in court I had this issue. Was watching a show on Netflix and it just kept buffering. Switched over to the same show on Xfinity and it loaded right away and streamed in HD. Back to Netflix and it throttled. Opened Speed Test. Told me that My speeds were fine. So yeah, Comcast is doing for internet what Volkswagon did with cars. "Is this a test? OK lets lie."

And for some strange reason when you use Comcast's own speed test on their site the results match what your plan is. But when you use 3rd party sites their results are similar to each other but are lower than comcast's...

 

again...strange.

my guess is that vodafone caps it at around 50 Mbps then, since that's enough to not worry about loading speeds and it preserves their bandwidth

Funny when site launched I was getting throttled 50 percent by Comcast now I am not. I guess Comcast was like aw man Netflix you had to show that we where cheating our customers and had to stop cheating before FCC got them in trouble especially because tom wheeler is Comcast customer.

You actually should expect to see a small drop because you have to leave their network to get to the other speedtest whereas the one on their own site is within their network. So if your traffic is routed through a slower Autonomous System (aka, another network) then you're speed will drop. The actual loss SHOULD be minimal 99.9% of the time and if it's much lower consistently then you're being throttled.

LOL I have a 70mbps plan with Comcast and even with their own speed test to the closest 'in-network' node I only get 1/3 of what I pay for. 

 

It's their peering agreements that do the throttling. Even if you have a huge pipe to Comcast, doesn't mean Comcast has a huge pipe to the rest of the internet. There needs to be more truth in advertising.

57 on Fast and 57.09 on Speedtest (Bright House, which is technically Time Warner I forgot Charter bought out Bright House and Time Warner, so Charter technically). So, no throttling for me.

Its funny because I'm only supposed to be getting 35...

Fast: 47Mbps

Speedtest: 78Mbps

 

I doubt I'm being throttled since I'm using a VPN. So probably a poor connection to Netflix servers.

 

I'm on AT&T U-Verse, business line.

 

*Edit, just retested without my VPN on.

 

Fast: 75Mbps

Speedtest: 80Mbps

 

So either something is throttling VPN connections or the path I'm being taken through with my VPN is poor to Netflix.

 

I use PIA and I have great speeds when downloading from Steam/Origin/etc. so my VPN provider isn't crap lol.

I have no idea exactly how fast my internet speeds are, but I'm getting like 8.5 Mbps down, probably because I have someone playing online and someone watching Netflix. Something I find kinda funny is that my upload is almost 10 times as much as my download, being steady at 70 Mbps. The magic of massive internet speeds is real.

I take that into account. If I see a 5-10 Mbps difference I wouldn't bother but sometimes I see 20-30 Mbps differences between Comcast's site and 3rd parties (all of which are consistent with each other more or less).

Yah, that's where you start to suspect Comcast is throttling you or something is messed up along the way like a bad cable.
