I tried  a run of 1000 non-linear fits (i.e. all the time is spent in 
"nls" and friends).
I found no significant difference in the system.time() output (2.1.1. 
seemed even a bit slower). both took about 22-24 sec. did a miss something?

(I installed only the framework and used the terminal version).

a question on the side: would it be a bad idea to install the 
R.framework with a name including the release (i.e. R.2.1.1.framework) 
and than use a place holder symlink R.framework? in this way switching 
between releases would  be a bit easier.


one more observation: the readline functionality is not complete, i.e. 
ctr-R does not work for accessing the command history.
