Subject RE: [ib-support] [OT] Software Network traffic sniffer

Thanx Helen and Doug.

Ethereal was exactly what I was looking for.
If you think it is too complex to use you've never used a
hardware-sniffer :-)
All in all it is solid, and exports its dumps into many formats, so that
I can analyze them just as I used them to do....

I can only encourage everyone to use such tools when building C/S apps,
as they will reveal any weaknesses in your programming style...

When we used to do the network-benchmarks on standard-application
software, we had differences around 2500% in network usage, and the
packet size/roundtrips even diverged further. This can be very easy
transferred into overall performance, as the network is very often the
bottleneck in large installations.
