There are 3 packages (compliled for my version anyway) on CRAN whose  
titles contain "benchmark". I have experience using the "rbenchmark"  
package which has a very simple syntax and would definitely meet your  
minimal requirements. From reading postings on r-devel but no direct  
experience, I suspect the "benchmark" package may be more full-featured.
