What is your dataone speed?

[baccilus]

Since yesterday i am getting a download speed of just 25Kbps(bytes). I am on the home500 plan. Is any one else having the same problem? have they again changed the speed or any thing. I am rnning ubuntu.

[napster007]

Internet connection speed results: <FONT color=red size=3> var speedtester_Img_name;if (bandwidth_KB

sorry abt that dint come well. i gert speeds upto 150kBps. i'm just using a mtnl 256unlimited connection

dataone home 500 plan user here,running ubuntu and Debian Linux-getting speed constantly at 225-230 KB/s or 217 KB/s -some days when rain hits bad

@praka

Dats an imp. reason y ppl shud shift to ubuntu. Evn I m getting bettr speeds in Ubuntu wit BSNL GPRS den in WinXP.

[Charan]

^^ Me too getting insane speeds in ubuntu ... Const 255-230 KB/s

[zyberboy]

Getting speeds around 230-250kB/sec in Windows xp sp2
not much different frm ubuntu and pcLinuxOs.
some days gets insane speed of 900KB/sec!!,dont know how....once downloaded 50mb in less than 50secs

there is something(pls dont kill me!-i dont know much more ) like MTU(maximum transmission unit) inhibited to 1492? in GNU/Linux rp-pppoe.that may be the reason for a little more speed ?
OK .I found a link which explains this things.read below quote and say thx

Max MTU: How do I find mine?

The MTU setting controls the maximum ethernet packet size your PC will send (you did know the Internet works in packets, didn't you?). Why a limit? Because although larger packets can be constructed and sent, your ISP and Internet backbone routers and equipment will chop up (fragment) any packets larger than their limit. These parts are then reassembled by the target equipment before reading. This fragmentation and reassembly is not optimal.

MTU and Windows and Defaults
Unless otherwise set, Windows defaults MTU to 1500, or a lower value of 576 for external networks. 1500 is OK unless you are running PPPoE, want to use IPSec (Secure VPNs) or both, then it's too big. 576 is not efficient for the broadband/Internet; it's too small.
Finding the largest MTU, by EXPERIMENT
If your MTU is too low already, maybe 576, the following method will not be able to detect whether you can switch to an optimal size. So first follow "CHANGING MTU for PPPoE" to reset MTU to 1500, reboot and then come back to this!

The best value for MTU is that value just before your packets get fragmented. How do you find that out? By using Ping at an command prompt.


Windows 2000/XP users:

Go to Start/ Programs/ Accessories/ Command Prompt and type the following:

ping -f -l 1472 www.dslreports.com
(That is a dash lower case "L," not a dash "1." Also note the spaces in between the sections.)

Linux users:

ping -s 1472 www.dslreports.com

OS X users:

ping -D -s 1472 www.dslreports.com

Linux and OS X commands are case sensitive.

Press Enter. Then reduce 1472 by 10 until you no longer get the "packet needs to be fragmented" error message. Then increase by 1 until you are 1 less away from getting the "packet need to be fragmented" message again.

Add 28 more to this (since you specified ping packet size, not including IP/ICMP header of 28 bytes), and this is your MaxMTU.

Note:If you can ping through with the number at 1472, you are done! Stop right there. Add 28 and your MaxMTU is 1500.
~~~~~~~~~~~~~~~~~~~~~~~~~~~


For PPPoE, your MaxMTU should be no more than 1492 to allow space for the 8 byte PPPoE "wrapper," but again, experiment to find the optimal value. For PPPoE, the stakes are high: if you get your MTU wrong, you may not just be sub-optimal, things like UPLOADING or web pages may stall or not work at all!

I have set to 1472( i use Linux Debian) as it seems working good for me

[baccilus]

I am using ubuntu too. Will see for a couple of days if it improves and then complain.

[praka123]

another reason which i got to know is all windows os keeps 20% bandwidth for M$ service(that i dont know!).there may be unofficial tcp/ip.dll patches may be

and Linux does not take ur bw anyway!
Overall, Linux is faster because it's better designed and thus it requires less resource hungry security software.
