Low bandwidth in linux

I m using a Redhat linux AS 4 proxy server in my office,in which I configure squid 2.5 for sharing the internet(BSNL dataone leased line).the band width provided by the ISP is 2 Mbps,but when I check the bandwidth in from the proxy server it shows around 400 kbps. is the official bandwidth testing web site of BSNL dataone (ISP)

Then I connect a dual boot client pc ( windows XP sp2/fedora 6) to the same port I use for the proxy server in NORTEL 8300 switch.Now I got the increased bandwidth (around 1.77 mbps) in XP but again low bandwidh with fedora.

plz tell me why linux operating system show me the low bandwidth ?

Bandwidth is related to several factors:
- dedicated vs shared "on-ramp" (DSL is dedicated, good)
- Ethernet card used in the machine (single vs. dual buffers and piplining vs non) - don't know but it may be the card, more expensive cards are often worth the cost.
- drivers for the cards. If the Linux drivers (older than the Windows versions usually) don't allow for the dual buffers or piplining capability then you won't get the rated speed.

You may also have issues with the wrong drivers for your card. It may work but not work well - timing is everything with drivers.

Your description says that with another machine (a different card and drivers) it almost works. It is NOT the operating system. Typically Linux is faster on most things than Windows. It is NOT the BNSL provider. Has to be the card or its drivers.

Linux operating system show me the low bandwidth

This sounds like your Net cards are limiting your Band or that in your linux boxes you have set a bandwidth limit somewhere.

Hello Sir,

As my internet is shared through cc proxy
I have to put proxies to all of my programs so that they can run.
Unfortunatelly the only one I cannot get running is outlook express.
When I try to edit the outlook proxy settings it sends me to Internet Explorer's settings
(which makes me think that outlook and internet explorer share the same proxy settings).
The strangest thing is that IE runs with no problems
but outlook express cannot connect to the server.
It says that the server cannot be found (both incoming and outgoing)
Could you please advise me how to make the outlook running.
Also I had try to install squid 2.7 proxy on win2k8 but i m getting some error with squid service is not runniong on win2k8 it says create services failed ...please advice me which proxy server i can use our network ( my task is only i want 2 secure internet & block some sites on my internet and outlook should be a work )

Thank you very much.
Have a great day,
