            Status: NEW

Build Information:

--
While testing with the capture files attached to Bug #3737 I noted very slow
and CPU-intensive Wireshark performance when displaying frames with many many
nodes in the Packet Details pane and multiple large byteview tabs in the packet
Bytes pane.

These capture files do represent an extreme and are definitely stress
Wireshark: in one of the files there are ~250K detail pane nodes and two 4Meg
byteview tabs associated with one frame.

It might be quite useful to do some analysis and testing to see if there are
any improvements which can be made without too much difficulty.
