My typical tests for performance with C++ are to start OO.o writer, then time "attach" or "bt" or "thread apply all bt full", depending on what I am interested in measuring. I picked this just because it is big, written in C++, and uses a lot of shared libraries. FWIW I believe we can have both correctness and good performance in this area. Tom
