i need an expert opinion.
Where I work, we have a private MPLS network that connects over 25 remote sites to our IT center (Server Farm). We have a 100 Mb link between the IT center and the cloud . All other sites (Montreal and Quebec area) vary in speed.
The ISP that handles our MPLS network just install a new remote site situated in Toronto at 100 Mb. To confirm that were getting the promised throughput, I use a tool called Iperf. Simply, it's a Client-Server DOS application that sends packets and measure the throughput of the network.
Iperf is telling me the throughput between Toronto and IT center is around 30 Mb.
According to me, i should be hitting the 70 Mb mark. Speaking with my ISP, their telling me it's because of the distance (latency) that i'm getting this result (they can't do anything about it). I'm having a hard time believing this explanation. All my other sites including quebec city (running at 5 Mb) respect the speed that were paying forâ¦ the problem is with the Toronto site.
Starting from the IT center, tracing to Toronto, i go through 5 hops and quebec city I go through 4 hops. Can one more hope make that much of a difference ?
Pinging Toronto, I get a average of 23 ms. Pinging quebec city, I get a average of 17 ms.
I agree that the packet has to travel a longer distance, but I wasn't expecting that much of a low throughput.
Any opinions is greatly appreciated.
