We've already had similar benchmark result done, while removing emem slabs: http://www.wireshark.org/lists/wireshark-dev/201303/msg00101.html http://www.wireshark.org/lists/wireshark-dev/201303/msg00105.html
I tweaked some things in r52568, r52569 and r52573 that had a fairly substantial improvement when dissecting with a tree. "tshark -V" is as much as 18% faster in my tests, and filtering should improve a little as well, though that is much harder to measure.
Still good we regain this performance (and even better tree free now is O(1)), even if tshark -V might be not normal use case. Thanks. Cheers, Kuba. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
