You load it into kcachegrind.  I found a compiled windows version on
sourceforge (I think http://sourceforge.net/projects/precompiledbin/).

Could they analyze perf results or run git bisect to find the point

Since this is on Ubuntu (which can run valgrind) just use the -p option
to tools/valgrind-wireshark.sh and it will produce a performance profile.
Do that for >both builds and we'll have something to work with.

Evan

Here's the output from "trunk", how do you get anything useful from it?

PS I suspect some new heuristic dissector has been introduced, since none
of the other changes from 1.8 to trunk are likely to have such a

Hi,

I recently supplied some people with an internal build from recent
trunk and got complaints on performance. Switching back

To the default Wireshark on the Ubuntu 13.04 system 1.8.2 reading of
a 400M trace file with SIP Diameter etc traffic is more than twice as
fast.

Regards

Anders
