I am currently using extensively a script with +250 lines that performed the 

3min 26s as first run
2min 57s in the second run and with several objects in memory

My script performs calculations of bayesian probabilities over 11 variables of 
1033 observations, uses no special library, performs several disk writes to a 
networked nfs exported directory and does the clean up of all explicitly 
created objects.

BTW, I currently use R 2.2.1 and it seems much faster than version 1.9 that I 
used before.
