Currently, with that fix, I get results like $ time ./tshark -r /tmp/nothing.pcap real 0m1.407s user 0m0.312s sys 0m0.676s with the extcap directory in place and results like $ time ./tshark -r /tmp/nothing.pcap real 0m0.334s user 0m0.182s sys 0m0.146s with the extcap directory moved out of the way, so the extcap executables are taking some time to run, but it's better than wasting time trying to run androiddump.c or Makefile.am.
And, if I move various extcap executables out of the way: $ time ./tshark -r /tmp/nothing.pcap # all executables real 0m1.484s user 0m0.313s sys 0m0.720s $ time ./tshark -r /tmp/nothing.pcap # after removing androiddump real 0m1.179s user 0m0.287s sys 0m0.588s $ time ./tshark -r /tmp/nothing.pcap # after removing ciscodump real 0m0.950s user 0m0.254s sys 0m0.491s $ time ./tshark -r /tmp/nothing.pcap # after removing randpktcdump real 0m0.688s user 0m0.228s sys 0m0.334s $ time ./tshark -r /tmp/nothing.pcap # after removing sshdump real 0m0.493s user 0m0.198s sys 0m0.235s $ time ./tshark -r /tmp/nothing.pcap # after removing udpdump real 0m0.335s user 0m0.183s sys 0m0.145s So that's about .3 seconds for androiddump, about .23 seconds for ciscodump, about .26 seconds for randpktcdump, about .19 seconds for sshdump, and about .16 seconds for usbdump. So none of them are individually out of the ordinary, but about 1.5 to 2.5 seconds per program, with 5 programs, adds up. ___________________________________________________________________________ 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
