Subject: Memory profiling/benchmarking

As a project for a computer performance analysis paper I am taking this semester,
I am going to look at the performance of the memory manager in R, with the aim of
determining how fast it is and which areas most need improvement. The idea is
that I will compare various versions of R, starting with 0.64.2, and then at a
few stages in the implementation of the new memory management scheme (of which
the first step was the hash tables for environments).
I am looking for scripts to use as benchmarks for memory related activities. As
a starting point I will use the tests distributed with R, but any other
contributions would be helpful. I don't think the tests I have are particularly
aimed at performance, but they should give a reasonable indication of which
functions are the performance hogs.
Any other suggestions would be greatly appreciated.
