[rest deleted] You need an ECM. I cannot reproduce your issue. This runs in the same amount of time, whether I execute the src block or run the code from ESS: #+begin_src R :session write.csv(diag(10)[rep(1:10,100000),],file="abc.csv") #+end_src #+begin_src R :session :results output system.time(read.csv("abc.csv")) #+end_src abc.csv is >25MB If the behavior you describe only happens with some files, I suggest you try to bisect them to find the issue.
