I have just tried alsamixer within ansi-term, and redraws in
response to Ctrl-L take well over a second.
Strange. Does anyone else see this?
Context: Debian Jessie x86_64 / i5-2410M.
i also observe noticeable lag in the above situation, on both on
24.5 and on master as at d6ea6453. The lag is worse on the latter
than the former.
Can you show a profile ("M-x profiler-start RET") of the slow
redraws? Preferably with the latest pretest of Emacs 25.1, if
you can.
Running the profiler on master:
#+BEGIN
- term-emulate-terminal
4233 91%
- term-handle-ansi-escape
4065 87%
