This happens because, by default, ESS waits for the output before
printing (we hope to lift this limitation some day).
If your problem is in the console, then you have to set
comint-process-echoes to nil in ess hook.
If your problem is with sending code from script buffer, then with your
version of ESS you have one option, (setq ess-eval-visibly-p nil). This
will make evaluation invisible (aka no printing of input to the
console), but instead it is much faster and doesn't stall emacs.
With the new version of ESS, released today, you have yet another
option 'nowait. With (setq ess-eval-visibly 'nowait) ESS will print the
input, but will not wait for the output. You can experiment with
ess-eval-visibly and comint-process-echoes directly from the ESS/Process
submenu. For this and many other reasons please upgrade to 12.09-1.
