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% - term-goto 3965 85% - term-down 970 20% - vertical-motion 4 0% jit-lock-function 4 0% - vertical-motion 4 0% - jit-lock-function 4 0% - jit-lock-fontify-now 4 0% - jit-lock--run-functions 4 0% - run-hook-wrapped 4 0% - #<compiled 0xa9010f> 4 0% - font-lock-fontify-region 4 0% font-lock-default-fontify-region 4 0% term-insert-spaces 100 2% redisplay 40 0% jit-lock-after-change 4 0% + command-execute 352 7% + ... 29 0% and 8 0% + redisplay_internal (C function) 4 0% + timer-event-handler 2 0% #+END

Hth.


Alexis.
