Currently libcxxrt is the default ABI lib for libc++ in Gentoo. I mean to replace it with libc++abi in that context. I'm interested in benchmarking to reveal the claimed difference in performance. Perhaps I can build the same program against libcxxrt and libc++abi respectively and see how it behaves. Do you have some hints on what kind of programs I should test? Thanks, Lei
