I have just updated to ESS 15.09-1 and I am noticing a dramatic change
in performance. For example, if I print a large-ish data.frame or
matrix, the iESS process becomes very sluggish, almost unusable. I
have replicated the problem when starting emacs with -q (and then
manually loading ESS). I thought it may have something to do with
Ubuntu or GTK, so I also replicated the problem from the command line
(outside of the windowing system). The problem is easily replicated on
my system: all I have to do is run something like matrix(rnorm(1e4)).
Then, every time I do anything in the iESS instance, the emacs usage
spikes to 25-35% CPU. Even simply hitting Enter causes a lag and CPU
spike. I am on Emacs 24.4.1, but have replicated on Emacs 24.3.
