the reason of 2.6.18 is explain there
that's RHEL-5 kernel related.
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.
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
For this reason, we moved in 2007 to --enable-kernel=2.6.5 since nobody
should still run a kernel that old.
