These days, memory bandwidth is a crucial factor for real applications, and may not be captured in benchmarks. If you are writing about performance, you should present some material on locality-of-reference and memory usage.
My Rails applications seem to fragment the heap over time, without obvious leaks (I've looked pretty thoroughly). And thus I think there's room for experimentation with the memory allocator running under Ruby.
