Hi,

Using windows:
Start > Run... > cmd (enter)
and then follow steps bellow:

C:\Documents and Settings\Administrator>tracert www.planet.nl

Tracing route to netapp.planettechnologies.nl [213.75.12.14]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  SpeedTouch.lan [10.0.0.138]
  2    21 ms     6 ms     5 ms  195.190.250.28

  4     8 ms     8 ms     8 ms  content54.wxs.nl [213.75.12.14]

Trace complete.

On *nix systems:

What it shows is route users go through to reach your server. The higher number, the slower connection is. The longer 'distance' they travel - more risk for bottle-necks. As you can see on the *nix traceroute I did, first 2 network components are on the same network as mine server and therefore really fast (under 0,5 ms). When I get 'out' of the network, things slow down a bit... Basicly, everything within 20-25 ms is reasonably good. Any higher then that and download 'jams' :(

Cheers,
Aleks

I would suggest those users to do traceroute to your server, to see what part of network is slow. That way you can pin-point where the bottle-neck is.

But if you can download fast, there is nothing wrong with your server...

Aleks

Thanks for responding immediatley. Thats' what I didn't understand. Is there anything to do with ISP location where our servers are located like max bandwidth or network router issues Users from london and sweeden also getting the same issues

Hi,
   I have one application which contians application server(tomcat4.0.4) on
App Lan and web server(apache2.0.40) on Web Lan located  at ISP provider in
newyork. Here I am storing all the files of size around 60mb on apllication server. when somebody(he is having broadband speed) from california tired to download
the file of size 60mb from the site, it took  around 70 minutes.

but When I tried to download it from newjercey It took around 6 minutes.
I didn't understand why it is taking that much time from california.
It sounds like there might be some net congestion between wherever your
server is and California versus New Jersey if the server load wasn't
significantly different at the times of the two different downloads.  You
can't control net congestion from your server, but I'd be happy to hear
other thoughts on the issue.
