ReadyNas NV+ 1.0 always has been very slow
Dear ReadyNAS Community, Ever since I purchased this device (ReadyNas NV+ 1.0) it has been extremely slow. I updated memory to 1gb Turned on all the check boxes in the performance tab Enable...
Ok, so, I moved the load from the ReadyNas NV+ to the Synology DS1512+ by enabling NFS on the ReadyNas NV+ and mounting the volume from Synology DS1512+. Then, I executed the rsync on the Synology without using the : or :: syntax (just using the file system).
The ReadyNas NV+ is only showing load from nfsd, while Synology is humming along doing the rsync. Now, I am seeing performance speeds up to around 27+ MB/s.
Lesson learned:
The ReadyNas NV+ has a limited CPU which is just good for sending data, but RSYNC kills it. So, it's better to mount the share using NFS and then run rsync on a machine with a faster processor using the file system (no host: or host::), or rsync over NFS.
Still, it does not take much to overwhelm the ReadyNas NV+ CPU, as just doing NFS creates a load of over 1.
Tasks: 59 total, 1 running, 58 sleeping, 0 stopped, 0 zombie
Cpu(s): 23.3% us, 37.1% sy, 5.4% ni, 13.5% id, 1.6% wa, 4.5% hi, 14.5% si
Mem: 1010656k total, 1003584k used, 7072k free, 10560k buffers
