MPLS Network and Circuit Speed
I work for a small credit union which has three branches in Pennsylvania
The software provider which hosts our banking software is in Michigan.
We use this provider for our banking software and document imaging.
We created an MPLS network (ping speed is >10 MS) between the three branches. Our banking software provider is a node off our MPLS network. Two of our branches have a 3-MG circuit (between them) and the third is 1.5 mg circuit. The connection (from the MPLS network) in Pennsylvania to Michigan (our banking software provider) is 3 MG. The 3MG circuits are all 2- bonded t-1 lines
The first circuit we were provided to Michigan went through 2 providers. The ping time between all three Pennsylvania branches to the Michigan router was between 68-80 Ms. We noticed especially when using the document imaging software the computers showed that they we not responding. Examples of latency are when scanning a driver’s license or loan document the PC would be “Not Responding”. These are new computers with 4 GB of memory. Also, when pulling up copies of the scanned imagines it’s was much slower (up to one and a half minutes) until the document loaded. Paging between the document pages could take up to 55 seconds
Because the circuit went through another Telco-provider troubleshooting did not seem to happen- all I was told that if you’re less than 80 MS that is an acceptable speed
I complained until I was blue in the face and told them that we wanted a new circuit through one provider. I knew this was possible since a local credit union in the area has the exact setup to the same software provider. I went to this credit union and was able to ping the same data center at the speed of 38-48 Ms.
I did run TRACERT on my original circuit and noticed it was slower where it was handed off to the second provider in North Carolina and Dallas Texas before it went to Michigan
In March they did come through with the new circuit. In the beginning it was actually slower than the old one-(speed was 72-88 MS)
I complained and they have gotten the speed reduced to 47-53 Ms. I have noticed a reduction in the amount of time the computers say they cannot respond- the slowness is more prevalent when opening a scanned document vs. when scanning a document
Can someone tell me is 47-53 MS on this circuit slow?
What tests should I be running?

ASKER
I manage my own routers, utilzation of the pipe has never reached 40%
We seem to only have issues retriving documents that were imaged
Everything else seems to be fine

So there are many potential reasons this could be happening, however, you should first verify that you have your systems (server/Desktops as well as network devices) configured and operating properly. 47-53 ms from Pennsylvania to Michigan doe snot sound bad, I am in Maryland and I am getting 64ms to Michigan.
Perhaps the problem is application based? perhaps you need more bandwidth? do you know your utilization on all WAN interfaces? Do you manage your routers?
