Sorry, I forgot to add the operating system, I am working on a Mac and
I do not observe the mentioned problems on a Linux installation of R
2.5 and ESS 5.3.4

Meanwhile, I found out that the problem is dependent on the presence
of a saved workspace in a .RData file. For example, if I start R with
ESS in a new directory that does not contain a .RData file, it takes
2-3 seconds to show the prompt and this message appears:

> if(!exists("baseenv", mode="function")) baseenv <- function() NULL
> options(STERM='iESS', editor='gnuclient -q')

After generating a .RData file by creating a vector a<-c(1:10) and
exiting R with saving the workspace, re-starting R takes about 45
seconds and a different prompt appears (without the aforementioned

[Previously saved workspace restored]


Starting R from the bash shell however does not show this difference.

Here is the output of sessionInfo():

R version 2.5.0 (2007-04-23) 


attached base packages:
[1] "stats"     "graphics"  "grDevices" "utils"     "datasets"  "methods"  
[7] "base"

Staring R with version number does not work for me, and unfortunately
I do not have the previous ESS on my computer anymore.
