Just the test on IA64 (Itanium2, 1.6Ghz, 8Gb memory). The results seem to

What libc are you using exactly? Can you try it with the unrolled
strlcpy I posted?
glibc 2.3.5 , gcc 3.4.4
my results were obtained already with your unrolled version (but when I
first ran it with the 'default' strlcpy the results were the same).
In glibc-2.4.90, there seem to be out-of-line assembly code
implementations of strncpy for: sparc64 sparc32 s390x s390 alpha ia64
and an inlined assembler version for i386. So the x86_64 case is
nearly the only popular architecture that doesn't seem to have
a hand-hacked implementation ... which throws some doubt on Mark's and
my results as possibly not being very representative.

Sergey
