Hi,
I have had a room of 12 people with 6 machines (Win NT 4.0 SP1 and SP4)
running Ethereal 0.8.6 with the latest libpcap for Windows.
On a number of occasions we had hangs, where Ethereal was consuming 100%
of the CPU. Sometimes the kernel was consuming large amounts of CPU,
and on those occasions, we could not regain control except by using the
master reset. On other occasions we could kill Ethereal and get control
back. Windows stinks!
I had always assumed that this was due to faulty architecture in windows.
In brief, CPU consumption/utilisation could rise to 100% given certain
network events owing to incorrect (or missing) scheduling inside
windows.
It may be stretching a point to suggest that nothing be done about this,
but it is probably not going to be considered to be a priority.
I may be completely wrong & even if I am right you know far more
about this than I do. I am grateful for the heads up, of course.
I have heard that the faster Xeon processors do not suffer
from this problem, if so, this must be one of the most perverted
pieces of evidence in the tapestry that can suggest that all software
problems can be solved with fast enough hardware known to us
at present.
Ben.
