工作学习 / IT技术讨论 / 我用的Smypatico DSL最高下载速度为360bps，Bell的网站宣称可达960bps，差别如此之大！不知你们的速度如何？

I've had one time with 3 download windows each with the speed of 71kBps, but only once. Most of the time 2x40kBps is the best. Single download sometimes can be over 70kBps.

KB, not kbps, otherwise it's even worse than dial-up, and I dont think you can stand it.

It is about 200K-300KBps within North America.

不会是cable或其它公司的DSL吧？

我用的是bell sympatico,按照它的宣传所说的应该是dial up(28.8 k)的一百倍,我用cuteftp下载大文件测试,基本可以达到这个速度,
Cable的实际速度比adsl慢,因为它是跟一个区域的所有用户共享2M左右的带宽,如果只有一个人上网就快,如果有几十个用户上网就很难超过100K

肯定到不了理论速度的。用Cable我最快是到了430K左右。平时一般是在200多。CABLE的下行应该是10MB共享吧？100随便上的了。

对不起，数字后少打了K，应为360Kbps和960Kbps。Bell sympatico的宣传所说的应该是dial up(28.8 k)的30倍，见http://bell.sympatico.ca/DynamicContentServlet.dyn?/english/hse/faq.html#q17

exactly! the bigger the file, the faster the transfer speed.

吹牛吧？要么把Bps和bps搞混了吧？两者差十倍的哦。记得搞DSL的专家yunflier(yunzhang)在＃31162中讲过Bell DSL的理论极限是1.5Mbps，约合150KBps。

you are wrong, Bps is equal to bps:bit per second.
-wins(wins);
2001-3-22
(#35963@0)
-
Bps=Bytes per second; bps=bits per second
1Byte=8bits for pure data; while tranfering, add 1~2 bits for error control
So, there are 10 times difference between Bps and bps.

In asynchronous transfer, the transfer speed is bit-oriented:BPS=bps=Bps. There is no sense for byte per second. However ,you calculation is partially right .For example, if the transfer protocol is 7bits data, no parity check bit, sending 1 byte will occupy 9 bits(ncluding 1 start bit and 1 stop bit)

And my company is the world's largest ADSL provider, so I thought I am quite familiar with the communication principle.

请问你公司是世界上最大的ADSL设备供应商还是ADSL服务供应商？
如果是前者，就不要自以为懂完了，从理论到技术到设备到工程实现到最终的服务，中间是有差距的

所以我说理论速度是无法达到的.更何况isp为了节约成本,会在设备端限制带宽.200-300kbps是正常的

Hi, I tested both under win98, if Bytes, it's shown as KB/second; if bit, it's shown as kbps. hehe

在North America 我这里的速度最高也就120多K （FlashGet) DSL的速度不是说与家里和BELL WORLD的距离有关么

possible. mine was usually ~500kbps, sometimes 700kbps, and last weekend it was 999kbps. But last night it was only 100kbps when connecting to etang.

My test: I just tried to d/l a 36MBytes file, the highest speed was 589kbps. But I feel sympatico is kinda unstable from last night, especially when I was using oicq. what I want to say is that the 'sending message' often got frozen for a while

Do you guys want to try this patch? http://www.speedguide.net/index.shtml, I believe it increased the speed at leat 10kBytes/s on my machine.

my bandwidth is always 1.2Mbps when I download a file from microsoft, why?http://www.microsoft.com/downloads/release.asp?ReleaseID=17030
it take me 5'20'' to gt the whole file.

maybe your registry setting is slightly different? I tried, at11:40pm EST,
it's 80+KB/second for me.

I think we are talking about the different things1.2Mbps is from the access manager, try it

For your information, EVERYBODY is using access manager if the service is HSE from sympatico.
