The size argument does matter that much, in glibc-2.3 announce with enable-kernel=2.4.0, the difference was 1%. Speed difference may be bigger. http://sourceware.org/ml/libc-alpha/2002-10/msg00048.html Drepper had answered (in an old message that I no more find) from to a breakage with enable-kernel=2.6.0 that there is no more a reason to stick to 2.6.0. For this reason, we moved in 2007 to --enable-kernel=2.6.5 since nobody should still run a kernel that old.
