Strange Download Speedtest Results
 

I seem to be getting a strange first reading using Robin Walker's Speedtest. Each time, the first test produces a much higher result than tests 2 -4 despite deleting temp files and repeating from the source server. I'm on the 2Mb service.

I'm no expert, but was hoping that somebody could explain the reason.

Thanks.

Strange that the transfer rate on the first result is exactly the same as well.

Try the forum speed test as it downloads a larger file so will give more accurate results for higher speed connections.

Chris,

Thanks for the quick reply.

The 1st test result is often 10005, but does vary between 9k and 17K!

Using the forum speedtest a couple of times, I received the following:

1st 512K took 1687 ms = 303.5 KB/sec, approx 2501 Kbps, 2.44 Mbps
2nd 512K took 2172 ms = 235.7 KB/sec, approx 1942 Kbps, 1.9 Mbps
3rd 512K took 2156 ms = 237.5 KB/sec, approx 1957 Kbps, 1.91 Mbps
4th 512K took 2141 ms = 239.1 KB/sec, approx 1970 Kbps, 1.92 Mbps

Overall Average Speed = approx 2093 Kbps, 2.04 Mbps

Overall Average Speed = approx 2096 Kbps, 2.05 Mbps

Whilst not as dramatic, the first test result is still unusully high.

i have had weird speeds with ntl internet.

the freakiest thing ever was uploading at a peak rate of 3.25mb/s [netmeter]..... well it must be uploading at something like that for a little while, as i went down, came back up to the comp after 20 mins to find that 500mb had been uploaded...................

Re: Strange Download Speedtest Results
 

Yes, those "legal" linux distros can take alot of uploading :)

Re: Strange Download Speedtest Results
 

linux? i think that is an OS.. well i use windows xp home?

and my upload is only meant to be 11kb/s anyway, so y would i upload huge amounts?

Re: Strange Download Speedtest Results
 

It happens, occasionally the kit at ntl's end doesn't police your downstream speed properly, so as in your case you get a huuuuuge burst to start with then it settles down as the ntl kit manages your bandwidth down to the 2Mbit you are paying for.

Just enjoy it really :)

if ntl accidently didnt police my speed I would see no difference the bandwidth isnt there :)

Sometimes I get a huge burst at the very beginning and end up with 10Meg speeds (through a Samsung STB I may add)
