Please check that the From: line contains a valid email address. After a delay of up to one day, you should receive an acknowledgment at that address. Please write in English if possible, as the Emacs maintainers usually do not have translators for other languages. Please describe exactly what actions triggered the bug, and the precise symptoms of the bug. If you can, give a recipe starting from `emacs -Q': The window scrolling performance ("multi-term" and plain old "term" in this case) in emacs 24 is terrible after a few thousand lines of scrollback, slowly getting worse and worse and after about 5000 lines of scrollback takes about a 1/2 second to render the next chunk of text. How I can replicate the problem: emacs -Q M-x term find / (The output of the find command whizzes by, and then starts to get jerky and slow when scrollback history is > 2000 lines) I've installed the stock emacs24 from linux mint/ubuntu packages (24.1.1), and a custom compiled version of 24.3.1 without any special tricks and a compiler option of -O3 and the term mode behavior is all the same, and this behavior even shows up with "emacs -Q". It seems the same with multi-term, ansi-term, nterm, it doesn't matter. This does work very fast in eshell and in terminal-emulator mode. What is weird is ALL the terminal modes in Emacs 23 seem to work great, but not Emacs 24. Any ideas how I can make this mode faster? My suspicion was around font-lock-mode but I've turned that off with no effect. The fact that it is still slow without my init file using -Q and seems to be really fast in Emacs 23 has me stumped. If Emacs crashed, and you have the Emacs process in the gdb debugger, please include the output from the following gdb commands: `bt full' and `xbacktrace'. For information about debugging Emacs, please read the file /usr/local/share/emacs/24.3/etc/DEBUG.

Both term and ansi-term and significantly slower than eshell when running "find /". I had a suspicion that it was because of term-buffer-maximum-size, but setting this to 0 made no difference. (BTW, maybe the default term-buffer-maximum-size should be raised from the default 2048? For example to (* 4 2048).)
