Adsl speed increase?

[Leftfoot]

Well yesterday I upgraded my router pots ADSL modem to the ADSL 5102G router with WI-Fi (because Telkom supposedly gave it to me for free....I gladly accepted ... and am now tied into a new contract)

I now notice, with all cache cleaned, that on the Telkomsa speed test my speed has increased significantly. I have ADSL 512 and have usually had about 480Kbps on the tests. Now Im getting between 603 and 611Kbps.

Your line speed is approximately 603.1 Kbps or 73.9 kBytes/sec
( Where kb = kilobits and kB = kiloBytes )

My friend has also seen some marked increase in his ADSL 384 line (although no router change here). Is anyone had this or has Telkom kicked off all the high end users resulting in the smaller fry getting a better deal?

hmmm
I should go try mine out too

They changed it and probably made some silly mistake and now it works out the time incorrectly or the code is less than 500kb. If you look in the code of how it works I'm sure you'll fine some evidence of unfair play.

I noticed their test shows higher speeds lately.

I have a friend whose 512 ADSL runs at 620kB/s - my 1024 runs at 4mb/s

Download time: 9.219 seconds
Size of file: 500 KiloBytes
Estimated line speed: 442.6 (kilobits/second)
Estimated line speed: 54.2 (kiloBytes/second)

384 line.

Haven't noticed any speed increase during normal use so I'm guessing something's wrong with their speed test.

322kbps on iBurst speed test.

If you select just the "junk data" that the Telkom speed test records, it is around 480~484kb...

So not quite the 500kb that the speedtest states

i think their speed test shows the wrong speeds- higher than its supposed to be.......take the sentech speed test for more accurate readings

Um... NO. The Sentech speed test is ***. The iburst and Telkom speed tests seem to be the more correct of them all. I particularly like the iburst speed test as it shows very accurate down/up stats.

 

[Wisemansa]

wats the site for the iburst speed test?

the sentech speed test i just tried it now.......it shows too slow speeds, the telkom shows too fast speeds.....or maybe im wrong i dont no

Telkom shows anything from 350bk/s to 470bk/s for me generally. I have never been able to download at higher than 390kb/s

Estimated line speed: 3575.8 (kilobits/second)
Estimated line speed: 438.2 (kiloBytes/second)

I'm doing well...

So here is what the telkom page uses to calculate your speed.
Now where they have set kbytes of data to 500, if you actually select
all the "junk data" its come to around 480~484(correct me if im wrong).


kbytes_of_data = 500; // data file size

linespeed = kbytes_of_data/downloadtime;
linespeed = 500 / 3 = 166.666666667

kbps = (Math.round((linespeed*8)*10*1.02))/10;
kbps = 1360

kbytes_sec = (Math.round((kbytes_of_data*10)/downloadtime))/10;
kbytes_sec = 167

Now if they actually set it to the correct amount of data, lets say
480kb(the actual amount of "junk data" then we would get the following results.

kbytes_of_data = 480; // data file size

linespeed = kbytes_of_data/downloadtime;
linespeed = 480 / 3 = 160

kbps = (Math.round((linespeed*8)*10*1.02))/10;
kbps = 1305.6

kbytes_sec = (Math.round((kbytes_of_data*10)/downloadtime))/10;
kbytes_sec = 160

So with just that slight difference in size it will give an extra 55kbps
and 7kb/s onto your linespeed.

This Can make quite the difference to a 384 and maybe 512 speed test...

There we go, thnx for the great explanation

I think this change probably happened when telkom moved the page or something because it always used to be accurate.

Those speed tests are merely an indication. I ran the Telkom test now and it reports +- 50kB/s for my 384kbps line. If I monitor DU Meter whilst the test is running, it doesn't go over +- 39kB/s. The same applies to downloads, local & international.
