Dennis,

 

The obvious think to check is the latency. Remote usually means more latency and if the protocol is not design to do this efficient you will get poor results on remote locations with a higher latency.

 

Compare packet captures for both client and look carefully at the timing. I expect that you have taken time to look at the various instruction clips on youtube regarding latency and Wireshark.

 

They will teach you a lot.

 

Met vriendelijke groet / With kind regards,

Hugo

Onderwerp: [Wireshark-users] How to find the bottleneck?

 

Hello,
the following scenario

headquarter:  Server (AIX) and client (Windows)

branch: client (Windows)

 

If the Clients from the branch open a project from the server in the headquarter
it takes about 5 times longer than the same project open in headquarters.
The bandwith from the branch is 1 GB/s for the hole company.
So OK it takes longer in the branch but 5 times.

The Data is on the Storage System.

How to find the bottleneck in the network ?
The networkadmin is sure all is fine.

 

made a IO Graph from "tcp.seq" from one of some sample Data I got from the Users

 

SPW = BAD = branch

SPG = GOOD = headquarter

Thanks
Dennis
