If you are using Linux, you could do 'valgrind --tool=callgrind --trace-children=yes ./wireshark' then afterwards browse the biggest of the resulting callgrind files using kcachegrind.

On Linux:

Unpack the source code and run configure with the option --enable-profile-build.

./configure --enable-profile-build

Then run Wireshark and do whatever you want to test.

Exit Wireshark and run the following command from the source directory.

libtool --mode=execute gprof wireshark gmon.out
