it’s not a super sophisticated benchmark… but instead of rsyncing directly to QNAP i NFS-mounted a shared folder:
and rsynced into that mounted folder… (i think rsync is way more CPU intense than NFS so it should perform way better on a ARM-based-NAS)
under OSX i had 17MByte/Sec which is not a SUPER FAST result… it’s kind of okay.
under Linux KNOPPIX 45-50MByte/Sec (directly connected via LAN, no switch in the middle) which is good 🙂
you can clearly see that 8x NFSD processes are eating up almost all of the ARM-CPU’s ressources (63%) the rest goes to RAID-Mirroring
