Analysing traces for performance bottlenecks

[Sam Stickland]

Hi,

Are there any packages (or Wireshark options that I've missed) that can 
follow a TCP stream and determine the limiting factor on throughput. E.g 
Latency, packet loss, out of sequence packets, window size, or even just 
the senders rate onto the wire. I know how to analyse a trace by hand 
for performance issues, but it's relatively time consuming.

Googling for variations on "Analyse TCP stream limit throughput" didn't 
find anything.
