Hi,
Was wondering if someone can give me suggestions on a particular problem I
am working on.
We are experiencing slow problems with a custom application that uses a
telnet like protocol (unisys t27). I have chosen to identify the time spent
on the server and on the WAN frame relay link and use this to identify where
the most amount of time is spent and then drill down to the problem. The
reason I can't use ping etc. is because the packet sizes can vary depending
on the informaton carried. Ultimately I would like to create a model based
on one of the traffic generating tools for generic testing.
My initial thoughts are to run an instance of ethereal on both sides of the
WAN and capture traffic and isolate the latency introduced by the WAN. For
this I am thinking of synchronizing the time on both PCs and capture
relevant traffic.
Has anyone done anything like this and are there any tools that can be used
to compare both files and calculate latencies.
(We already have a way to identify individual transaction execution times on
the server).
thanks.
