Network Traffic Baseline compare performance issue

Network Traffic Baseline compare performance issue

Network Traffic Baseline compare performance issue

Hello all you networkers!

i got the following question:
sometime in our network my users come up with performance issues within a specific Software (clearcase Rational), i already checked alot of different things like intercabling between switches network card drivers and other stuff. I already asked to Rational IBM if there is a Software issue that it just takes some processing time for the next request.

anyhow i just did a tcpdump of my network, everytime when a preformance issue occured, so the error is in this dump. I already saw that after some requests the host does not send or receive anything for a period of seconds.
If there is a request i see that it is processed between server and workstation in msecs which tells me that the traffic seems to be ok, but then nothing happens except some stuff of the network or router itself for seconds.

has anyone enough knowledge to interpret this dump and could explain the seconds of nothing from the host ?
or is this just normal because the software does not send or receive anything for this time which then would be a software problem.
or are these dumps inbetween the reason?

I already tried to start a ping programm which runs the whole time, this reqeusts are sent in there "donothing" times, which tells me the network card driver is not hanging or something like this.

as i would interpret the host (workstation) itself does not send even one request for seconds isnt it ?

this is the host
10.10.99.x are the servers and 3 are the switches

maybe someone has another idea of interpreting or at least of checking some different way into this issue ....

thanks for your help in advance

cheers joe

RE: Network Traffic Baseline compare performance issue

I found the problem

The reason was a request from clearcase client resolving a special group which generated a call back to the domain controller, this DC did not have the groupe information needed and sends back an not_translated in an LSARPC response. the problem was that the DC did not have the group and it timed out with around 45 seconds, so after recreating this groups requested from the client in the DC everything works fine again. The problem is that the Client was waiting for this answer even it does not need this groups they where set in the .identity directory of all our vobs. deleting the groups from the vobs files and removing it from everywhere was the solution

so this thread can be closed
