Hi,

Running valgrind on my standard pcap we have gone from

==36946== Callgrind, a call-graph generating cache profiler

==36946== Copyright (C) 2002-2013, and GNU GPL'd, by Josef Weidendorfer et al.

==36946== Using Valgrind-3.10.0.SVN and LibVEX; rerun with -h for copyright info

==36946== Command: /home/ericsson/wireshark/.libs/lt-tshark -Y frame -nr /home/ericsson/etxrab/TCT_SIP_traffic.pcapng

==36946==

==36946== For interactive control, run 'callgrind_control -h'.

I’ve been testing the performance a little more and it seems that the loading time has increased not only for GTP protocol. I have sniffed a pcap composed by 22844 packets and if you open it up with both versions, v2.0 lasts 0.520s and v2.1 lasts 1.433s. But as you saw before for GTP protocol is even worse, I’ll try to get a pcap example that I can share.

 

Regards.

I can’t share this one, because it has user data and it’s confidential, but we are going to generate another one that can be share. We are using GTP protocol, if that gives you a clue.

You can directly add the text output of load time...

It is possible to share your pcap ?

Hello,

Here is the loading time difference between the v2.0 and the last automated build for win64 Wireshark-win64-2.1.0-875-g9779ae3.exe

Regards.
