Transfer Rates

[Sparky_za]

I downloaded Fedora Linux from the IS FTP site, just thought I'd post the results.

For 1 hour downloaded 801.39MB at a rate of 227.95KB/s. Using Download Express as a manager and Bitmeter to measure performance. Average for the total download of all 4 ISO's was 216.89KB/s.

Now that comes to more than 1Mb/s. Why would that be? I understand that using a download manager makes multiple connections and so speeds up the process (to make it simple) but surely it cannot go faster than the actual speed of the connection?

Just something interesting. Either way I am very happy with iBurst.

Eish...

I did the GamCo bandwidth test just for fun (don't we all!) and this was my result:

Your current bandwidth reading is:
2.34 Mbps

which means you can download at 299.59 KB/sec. from our servers.


How is this possible?! I had clean cache and everything before running the test.

Wow!!

Isn' the Ibusrt technology inherently capable of 2Mb/s?? Maybe they are starting to unlock this now!!

Doesn't really affect me!! All this means is that I will now get to my 1GB cap in less than an hour almost

yeah I've noticed since last night that my iburst which use to run at 30kb/s download speed was hitting 90kb/s... (pity for me I'm in a *** area to obtain all 139kb/s speeds

can't wait till they get Hyde Park Tower up and running!

It looks like they managed to sort out the CT problem, at least I hope so as the speed test I did a min ago is quite fast.

Below is the data used to calculate your download speed:

* Download time: 3.313 seconds
* Size of file: 500 KiloBytes
* Estimated line speed: 1231.5 (kilobits/second)
* Estimated line speed: 150.9 (kiloBytes/second)

Tansfer rates ....

Hi Guys

I now have a awesome signal, but am still not getting anything better that 40-50Kb/s. I have used utTraceStar to tweak my signal to -77db and a rating of 8/10 Very Good. My other settings are as follows:

Settings: MTU: 1400, RWIN: 255555, wscale: on, tstamp: off, select Acks: yes, mtu path disc: yes, black hole: no, max dupl Ack: 1, ttl: 64

I got my suggested MTU settings from TCPOptimizer. I have tried various MTU settings, including the IBurst suggested 1352.
No better.

Anybody got any suggestions on what else I can do to get my transfer rates up ??

Well if those rates are during the day then they are quite normal, run a speed test at about 10pm or so and post those results. All your settings are pretty much fine though, however my TCP Optimizer gave me exactly 1352, what WBS reccomends, maby 1400 does work better for you though.

Are you using a multi-thread download accelerator? That would help alot if you arent already using one.

The download rates I got were done on a Saturday, starting from around 9am. Signal strength is normally around -85. MTU is set to 1352. Connecting to tower 24 as stated by utTraceStar.

1400 MTU is not okay. Your data packets will get fragmented. The MTU should end in a 2 for Winpppoe (an extra 8 bytes in the header). 1352 is safest, but on my BS 1392 works without any fragmentation.

If you use an RWIN above 64K you need window scaling and timestamping on, otherwise your error rate may increase due to lost packets.

I've been very happy using an RWIN size just below 64K. For an MTU of 1392, I get an RWIN size of 64896... (1392-40)*48. Then you can then switch window scaling and timestamping off.

I can't offer any guarantees that tweaking will yield vast improvements, but it does no harm to try. And you never know...
