User is saying that the performance in the new building with new networking equipment is poor, but everything works well when he goes back to the old building. There are couple differencies how the network has been built (for example the new network is behind an internal firewall) but from what I can see from the FW/switches everything should be OK. There's plenty of BW and no errors on the switch interfaces or dropped traffic on the FW. When a colleague went there everything worked well without any problems on his laptop.
So, do you use any software that could either analyze mirrored traffic from a switch or one that I could install to users PC to measure the performance? As the user does whatever the user does, the traffic should be somewhat similar from day to day. I guess I'm looking for a software that could tell me the average response times for packets to servers A,B,C,X etc but without going in to too much details as it would require a lot more work to figure out how each app is working. Perhaps if there are lot more packets/retries/dropped packets/latency between the PC and server comparing to when the user is in the older part of the network I could figure something out from that, or at least have some proof that this is actually happening.
I'm not sure what I'm exactly looking for but thanks for any ideas anyways :)
