250MB capture file which takes 35 minutes to open

performance

asked 2021-02-09 18:50:22 +0000

I have a 250 MB pcap file with 170,000 frames, which takes 35 minutes to open with Wireshark 2.4.2 on my VDI. This file comes from Riverbed ARX. In environment where it was captured I can only access Wireshark 1.14, which opens this file in 5 seconds.

So, you might think that there is a problem with my VDI or my Wireshark 2.4.2 install. Well, I have other large files (e.g. 1.8 GB with more than 300,000 frames) which I can open in 25 seconds on VDI with Wireshark 2.4.2.

Any suggestions on how I can investigate and fix this issue?

This is probably caused by the amount of state which is being tracked across the packets when dissecting them during the load. What you can do is change the preferences of the dissectors involved to limit the amount of state being collected, such as reassembly, timestamp analysis, etc. Of course this requires some insight in the kind of traffic involved.
