hash-29 The XRH-2 Hash Function — performance on x86-64 (system x86_1)

Independent measurement following the structure of the NICCS x86 self-assessment guide, §3.5 (1)–(7). Not a submitter self-assessment.

5. Resource consumption

Static memory is approximated by the library's loadable ELF segments; peak memory is the process high-water mark (VmHWM) including the benchmark driver and libc, so both are upper-bound proxies rather than isolated algorithm memory.
