Can someone explain to me how doing a speed test on MYBB, the speed on International is higher for some than on local?
:confused:
According to Jannie, if I understand it correctly high pings will greatly reduce your speed.

So basically according to the stats that is not the case.
My higher ping international shows higher speeds as well as in real life my international downloads seem faster.

Local Mweb 4mb uncapped:

Good Morning Marine1, are the results the same on other speed test sites?
 




See?
So clearly this issue of ping affecting speed seems to be wrong.
So it would be interesting to see what the next reason is for BIS being slower than a 90yr old granny doing a 100m sprint

So tell me again how latency affects speed so much :rolleyes:

Latency is simply the time it takes for a packet to travel between one place and another, this will impact on speeds. The further the distance the more it will impact on your speeds (i.e. the higher the latency).

Internet 101:
When surfing the net if you request a website/file your machine sends a GET request,latency is the roundtrip time for any requests,so your GET request is sent and an acknowledgement is returned to you in approximately the latency time. Once acknowledged the site then transmits the data to you. Now while this transmission is going on ping has a lesser effect as the data is pretty much pushed to you,and your system only has to acknowledge every few packets rather than every packet,if the acknowledgement is slow the server will pause transmission waiting for a response

So in short:
Latency has a big effect on browsing due to the nature of sending and receiving requests ( perceivable )
Latency has a lesser effect on browsing/downloading speed due to the need for your machine to acknowledge incoming data packets to the server

Think of it in terms of cars,High torque may mean a good 0-100 time,but not necessarily a high top-speed

There is no direct relationship between latency and transfer speed. The latenycy, or RTT (round-trip time) measures how quickly a small packet can get from your computer to a server and back, however it does not measure how much data (how many packets) can be transfered in a given period of time. Two different ISPs with the same transfer speed, or even the same computer, at different times and when connecting to different servers can give you very different RTT values. Latency is related to the distance, as well as your ISP's peering arrangements, network congestion at the time, etc. however it does not relate to your available bandwidth or transfer speed.

With all that said, there is an indirect relationship between transfer speed and latency. For example, a packet takes time to travel from a server to the client, and there is a limited number of packets that can be sent (in a TCP/IP data transfer) before the server stops and awaits acknowledgement for already received packets in order to continue, so excessive latency can have a negative effect on transfer speed, especially with untweaked PCs on a broadband Internet connection.

Guys I know what latency is :rolleyes:

What I am stating and the facts are showing it in black and white is that it is not affecting the speed by any large amount.
It is also showing that Intl. is faster in sending the "test" packet on intl than on local.
I am linking this to the discussion I had with Jannie who was telling me that my BIS is dog slow due to a number of issues including latency.
Granted BIS and normal wireless internet is far different than fixed line however speed and latency issues should stay the same.
these issues should not change depending on the medium used.

PsyWulf, thats exactly what I was trying to explain to Jannie. Latency SHOULD not affect the speed at which a packet is sent

Well it does have an effect,especially with slower connections the effect gets compounded :P

As for the speed test results,it isn't really an ideal indication,just measures brute data transfer speeds after connection is established for a cacheable data packet. Reason I say that is those data speeds aren't supposed to be achieved on a 4meg account ( You should get around 420ish Kb/s flatlining the line ),leading me to believe you are getting cached traffic response or another anomaly ;)
 
Ok so now back to my original argument.
On BIS I am achieving 258k/sec
On normal internet APN, same phone same location, over 1mb.
Now tell me Vodacom are not throttling the BIS service? ;)
Latency is worse with non-BIS

AFAIK Vodacom just connects you to the BIS network. So slow BIS speeds would indicate that the BIS network is overloaded and that the problem doesn't lie with Vodacom. Especially because your normal internet APN speeds are so much better.
 
Likely the 10 billion torrent users sucking up the juice. The BIS pool is seperate from the 3g pool,wasn't it something like a 1gigabit pipe for SA?

Then why does MTN and Cell C not have the issue? ;)

If MTN and Cell C were also experiencing these issues then fine but they are not so one asks, are Vodacom throttling the BIS? My answer based on speed tests is YES!!!

Lower subscription numbers :P

MTN? Come on, you do not really believe that? So what you are telling me is it takes me about 2-5 minutes sometimes to open a MYBB mobile webpage due to too many numbers?
Well then with the 20 billion in profits, get another pipe :)
I know this thread has changed into a mobile discussion but the theories around the tech are the same. Latency VS speed.

Yes I do really believe that:
With higher subscriber numbers you have more abusers ( torrents,file sharing site downloads et al ). With a limited pipe the higher number of abusers can definitely degrade service :)

And no I don't think throwing bigger and bigger pipes at them is the solution,in fact you'll just attract more abusive behaviour
