Monitoring CPU and RAM Usage (linux-dash and alternatives)
I have had a RN104, (OS 6.4.2), for some time now but have often thought that it was running a bit slow. For example I have DVBLink TV Server installed and when opening it up from another device it o...
That was just my opinion. It isn't bogus or misleading, just only so much the little Marvell Armada CPU can do :) Honestly, has I said it serves up my media files perfectly. I just found running some of the varous apps (Plex, the Virus scan, pigwo, and enabling iTunes or DNLA) running at the same time while trying to access the files via Plex (streaming mkv files) it isn't effient and uses a lot of CPU. That is why I mentioned running top and saving the output so you can see the CPU use and Waits.
The way we have it set up is probably simple but more or less it is the centralized storage for our home. All of our computers back up to it. It also serves our media (Music and Movies) via Plex. Plex is running on Ubuntu and NFS mounting the NAS shares. Once a week the 104 sends its data to another PC in the house with lots of storage who shoots it up to Crashplan. Documents, photos, computer backups, and music mostly - I don't back up the movies since I have the physical media still.
Down the road I'm sure I'll expand my Ubuntu server with a raid card and ZFS or some other files system/RAID and remove the 104 since it would be significantly faster with regards to disk I/O and network. But so far NAS to TV or other streaming device it is ok and I can tolerate the 20 - 30MB/Sec transfer rate it seems to see when transferring files.
So yeah, it is good at one or two things but not for running Plex or some of the more CPU intensive applications while also serving up media. I think that is pretty fair to say. It really comes down to the CPU and Memory amount it has as the limiting factor.
Thank you all for your replies and advice. I have come to the conclusion that I may be expecting too much from the ReadyNAS104? ie just because it can do something, such as run DVBLink, does not mean that it can do it well?
I assume that this low end ReadyNAS was primarily designed to serve files / media and as saf1 mentioned in his post it does this well. The fact that it is also able to do other things at the same time should be seen as a bonus perhaps?
Apologies for the delay in replying - I'm having desktop PC problems.
