how to increase refresh rate in Wireshark IO Graph

[cskiraly-munka sunserv kfki hu]

Hi,

I was looking for a real-time network traffic graph generator, and the
best I've found was of course in Wireshark. Still, it has a refresh rate
of 3 seconds on my computer, even if my processor is 95% idle.

The reason seems to be a lazy refresh from Gtk, and I don't know how to 
give it some priority. Or should I explicitly trigger the refresh somehow?

I was trying to do a quick fix, but I've never been dealing with Gtk 
before. Anyone have an idea how to make it faster?

What I've done as a quick and ugly fix was adding a  g_timeout_add_full
() to the end of gtk_iostat_init() to schedule some periodic redraw events.
The one linr of code I've added was something like the following (sorry, 
no diff, I do not have the source here with me):

g_timeout_add_full (G_PRIORITY_DEFAULT, 100, io_stat_redraw, io, NULL);

(of course some other code is needed to clean up when the window is closed)

This one line reduced the refresh rate to 1 sec, already much better,
but I wasn't able to go below, even if I set the priority higher or the
event rate to some milliseconds. I'm sure someone knowing Gtk can
achieve much better with the right one line of code. Anyone knows the
solution?

Thanks,
Csaba
