Hi to all of you.
I need your advice for the following situation:
In our HQ office located in Italy Europe, we have 20 people accessing an Amazon EC2 instance in Singapore Region.
My colleagues are using Microsoft remote desktop to work on a legacy 64bit application.
Colleagues  are complain that the “user experience” is not the same of having the application here in the office … and the support team of the legacy application states that the network latency between the office and the EC2 instance is slow.

I contacted our Internet service provider (pipponet) and provided a tracert from both directions (see below) and  the answer is: that the latency reported is acceptable between Europe and ASIA (Singapore) and it is  intrinsic in the connections between international carriers. It cannot be improved ( I asked also the possibility to change the routing to reach the EC2, no way. )

My questions are :
1) do you think this latency is acceptable or not?
2) is really an Intrinsic value this type of latency ?
2) What can I do to improve the latency without changing the Region of the EC2 Instance?

Thank you
Carlettus


PS: I made a change of our providers name and ip addresses of both ends for security

From my workplace connection (german scientific network) I have a turnaround time in the traceroute of 342ms for the IP 175.41.128.234. So it really seems this service has bad connectivity. My traceroute looks totally different from yours.

I only need your advice on the data I wrote on my message.

without a proper trace from another location its hard to tell if your provider has a chance to increase the round trip time. But if the ip adress was only chqanged in the last byte it should be no problem. As geoip indicates the Target IP of your trace sample is in singapore too it can very well be the same provider/route for the given IP and the IP you have problems with.

But you might trace it yourself e.g. from other internet connections instead to see where the slowdown comes from.

If all providers you can test with show a similar turn around time it would be difficult to do something about it.

But all in all connections from europe to SE-Asia are in general quite laggy. Im suffering similar problems between HongKong and Germany.

Hello,
thank you , I only made the change to the last octet of the IP address.

As you said I made some test using an online tool at http://traceroute.monitis.com/ . The results is the same  ~ 360ms

I think I have al the info .
Thank you for sharing your trace .
Bye
