In what way to make it run faster? Wiresharks innards are quite complicated and may take a while to get the hang of but if it would be possible

To optimize in terms of memory usage or execution speed it would be very beneficial for the performance.

-          The packet list handling /ui/qt/ packet_list.cpp would be the place to start

-          Reassembly (epan/reassembly.c)

-          Conversations(hastable sizes and lookup) (epan/conversations.c)

-          Epan/proto.c

You’d probably need a large capture file and run profiling on it to find the hot spots which may vary depending on the protocol mix in the capture and

Whether the GUI version (Wirsehark) or the cl version ( tshark) are used and if filters are applied or not.

Subject: [Wireshark-dev] Greetings and Where to Start

 

Hello,

 

My name is Breanna and I am a junior Computer Science/ Cyber Security undergrad at the University of Notre Dame. I am currently in a Data Structures course which requires me to find an interesting open-source project to *hopefully* contribute to, using the knowledge I should gain throughout the semester in optimizing code using data structures. I recently heard of Wireshark through my Computer Networks course and I am very interested and would love to find a way to contribute. However, I have no idea where to start. Do you think there's any place in the Wireshark code where I could help? (Or maybe, if it seems Wireshark is not the right fit for me, do you know of any projects that could fit?)

 

Any help would be greatly appreciated!

-Breanna
