Wich one tool can help? - Slowly network (Clients to Server )

[IngGerardo013]

Hello guys,

I have the next situation,

Users have reported an excesive slowly troughput on their PC´s, these production´s  users just use (each user with a respective file and computer ) an specific file ( excel  file) to save information that they capturing on production area, when they try to save their file ( these file is acceced throgh the network and is located on a server) they see how computer take long time to save it (from 1 minute to 5min.). these users use a wireless network card(802.11g) . There are some APs I got the info. Of the ap that was giving network connectivity to one of the clients, the ap has  aprox 8 - 15 users average.

I sreen shot some statistics and these was the results:

Is a noise problem?

trouhput problem?

Sever problem?

is there a tool to view the troughput ? what should be the an healty trougput? how can I view the gut of the transmition client - server , server-client any tool software or cisco commands?

another tests that can make? what else can verify??

ANY INPUT WILL BE VERY APRECIATED,

Well you have multiple issues maybe... Take a look at jperf. You can load one on the server and one on a laptop. You can run a throughput test when the network has low utilization and then run one when there are issues. This will give you a throughput result and can eliminate if its throughput or maybe the server is being peaked. Monitor the server resources also. I have an excel file that is like 80 MB empty and to save that takes a while and that's local in my machine. That takes around 10-60 seconds or longer depending on the machine hardware. Again that is local saving.

If you think it's interference then you need a spectrum analyzer. So it's hard to tell you what you really need to so, but start with jperf and go from there.

Hey Sccott

I was testing the jperf, it works well, do you know if exists parameters that it says if the troughput is good/poor or bad?..

is/are there specific rules for trouhtput/bandwidth that tells you what should be aprox. your troguput?... is this helpful to see if there are packet loss(tests that I did, didn´t show packet loss) ?...
