Comment # 11 on bug 11515 from 
  I rebased code and included change 10553, but the load time for attached pcap
file is still 22 seconds for Qt wireshark. The elapsed time on Loading dialogue
is 17 or 18 seconds for GTK wireshark, but it still take a few seconds to have
content dispalyed in packet list pane, so the total load time for GTK wireshark
is also 22 seconds. It is strange that the elapsed time on loading dialogue is
increased from 14 seconds to 18 seconds comparing with previous software load
for GTK wireshark.
  The newest software load introduced the column resizing issue, see attached
picture.

Follows: v1.99.10rc0
Precedes: 

    Packet list speedups.

    beginInsertRows + endInsertRows is expensive. Instead of calling them
    each time we add a packet to the list, queue up a list of visible packets
    and flush it during the next UI update.

    Assume that none of our column data has newlines. Enable
    uniformRowHeights and only disable it when we need to. Note that this
    requires further work.
