Why does the extcap stuff take so long to start up?

$ time ./tshark -r /tmp/nothing.pcap # reading an empty pcap file # with all the extcap binaries present real 0m4.089s user 0m0.694s sys 0m2.637s $ time ./tshark -r /tmp/nothing.pcap # reading the same empty pcap file # with the extcap binaries removed real 0m0.540s user 0m0.310s sys 0m0.220s So it took *four seconds* of real time, and over *two seconds* of system-mode CPU time, to run, I guess, extcap_register_preferences(), and all the stuff it runs. Does it need to take that long? If it does need to take that long, do we need to do that if we're not capturing? ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
