I have just tried emacs 24 (24.4.1 from debian jessie). Compared to
version 23, mutt running within ansi-term is very sluggish. Terminal
redraws take several seconds. This is still the same with emacs24

I have noticed bug #18151 and wonder if it is the same, although it is
reported against an earlier version (24.3.92).

Moved to term-mode, and closing.
