Has anyone done this with the libc, or do they plan to? I doubt if anybody tried this; I certainly did not. Moreover, I doubt if such a testing can ever yield an answer that is generic enough. Any benchmark that is not tied to a specific application is more or less meaningless. In contrast, the library is not specific to any application. So theoretically you will need to link and benchmark a large number of different applications to measure an average effect. This is too much of an effort, and failing that, using switches which are said to supply the best overall performance should be good enough, IMHO.
