On what platform are you doing this, and what version of GTK+ do you
have installed?
I detected it on FreeBSD 4.8, gtk 1.2.10. I have reproduced it on
Mac OS X 10.2.6 with 1.2.10 of gtk and glib with a file of approx
100000 packets an 10MB on Disc.
One possible problem is that GTK+ isn't 1.2.8 or later (I think the
version was 1.2.8) - prior to 1.2.8 (or whatever the version was), it
appended to the list of elements in a GtkClist (the widget used to
display the packet list) by scanning to the end of the list and adding
there (the word "quadratic" comes to mind here...); I sent them a patch
to use the end-of-list pointer that was already present, turning
quadratic into linear, and I think it got into 1.2.8.
(Actually, that particular process should take a constant *time*, not
proceed at a constant *rate*, but to do that, I need to get the
"virtual
clist" stuff working, and to do *that*, I need to get some other stuff,
such as support for reasonably fast random access to gzipped captures,
working....)
