DGalt Posted January 28, 2012 Share Posted January 28, 2012 I've had my server set up for about a year now. I hadn't ever really though about this, but my transfer rates seem rather slow considering my network / hardware. So my network is listed as a gigabit network. Both my desktop (which is what I usually transfer files from) and my unRaid server are connected directly to an Airport Extreme router (gigabit LAN connections). The mobo for my server has a LAN connected rated for 1000Mb/s My transfer rates are always around 10MB/s. Looking at my network usage, I'm at about 10%, which would make sense if something somewhere was limiting my network speeds to 100Mb/s Something just seems wrong here...networking stuff is not my forte and I really don't know where to begin trying to figure out what the issue might be. Any thoughts? Let me know what further info I need to provide. Link to comment
mikechy Posted January 28, 2012 Share Posted January 28, 2012 Does your array happen to be getting full or nearing full? What type of method are you using to fill the drives? Might it be writing to a particularly slow drive at the moment? Link to comment
DGalt Posted January 28, 2012 Author Share Posted January 28, 2012 The drive that I'm currently transferring to has about 300GBs of free space left (of 2 TBs). All of the drives are the same (5400RPM, Samsung drives, forgetting the actual name), but again it's not that these rates have changed...this is what I've been getting since I put the server together. I'm basically "cutting" files that are present on my desktop and "pasting" them to the "Movies" share (which only includes 1 drive at the moment), which is mapped as a drive. Link to comment
One2go Posted January 30, 2012 Share Posted January 30, 2012 Do a copy of a file using TeraCopy, it will tell you what speed you are getting during a copy. Without those stats you will not get many answers. I have eight 2TB Samsung drives SAMSUNG_HD203WI & one SAMSUNG_HD204UI. From my desktop machine to the protect array directly I get up to 45 MB/s but most of the times I get an average of mid to upper 30s. On a separate server a HP Micro Server I only get up to low 30s with 3TB Hitachi drives. It varies but I believe the copy / paste method may not be the most efficient for transferring.

dgaschk Posted January 31, 2012 Share Posted January 31, 2012 Verify connections speeds. Enter: ethtool eth0 on unRAID and check the speed at the client. Link to comment
DGalt Posted January 31, 2012 Author Share Posted January 31, 2012 So, connection speed seems to be 100Mb/s, according to that command: Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes Now the question is, why Link to comment
DGalt Posted January 31, 2012 Author Share Posted January 31, 2012 TeraCopy gives a rate of 11MB/s, which is about right if the transfer rate is only 100Mb/s. Still not sure why that's the case though. Link to comment
dgaschk Posted January 31, 2012 Share Posted January 31, 2012 Make sure the cable is CAT 5e or better. CAT 6 is needed for longer runs. Try a new cable. Test any wall wiring or use only direct connections. Link to comment
DGalt Posted January 31, 2012 Author Share Posted January 31, 2012 sigh @ cheap LAN cable. Had just assumed everything I had was Cat5... now I feel dumb lol, thanks guys...wire running from router to server apparently wasn't Cat5e. Getting more respectable transfer rates now Link to comment
