I posted the details on bug 5313, here a summary of them:
Setup:
A 9mb tracefile of a telnet session containing a binary data transfer between
client and host (so no lines).
When doing a follow tcp stream on this telnet session on my i5-540 2gb system
with windows 7 it takes ages to display the content in a windows.
when after several hours the window finally comes up scrolling is extremely
slow (also several hours on each move).
When reducing the # of packets (aka the file content) everything works fine.
I guess that the uses "text-editor" to display the content does not correctly
handle large files.
Maybe 2 ideas to solve this (at least temporarily):
1) configurable external text editor
2) direct export of a tcp stream as textfile without first displaying it
