    I know there are a number of these threads, but I can't seem to get my transfer speeds any higher than about 10 Mbps. I have gigabit everything (I'm pretty sure). Though my speeds are not particularly consistent and at best I'll get about 13 Mbps.

    My setup (all wired):
    DS-212j -> Linksys E2000 router (DD-WRT firmware) -> iMac (late-2007) w/Mavericks.

    I connect via afp, and tried with SMB as well but no real difference. Is there anything anyone can think of that would be bottlenecking my speeds? I have two Western Digital green drives which I think are 5400rpm. That still shouldn't be a bottleneck should it?

    Drives shouldn't be the bottleneck there...they can handle a great deal higher. What are you using to measure? Just a guestimate transferring a file? Try getting the free Mac app Blackmagic Speed Test and set the target destination to the root of your mounted drive. Post the results :)

    Good call, I forgot I had Black Magic. Originally I was estimating the speed by the Synology Dashboard which shows you activity. Anyway, Blackmagic confirms what I was saying 11.1 MB/s.

    Just to check I ran the test over WiFi also and it was getting 2 MB/s. Certainly something's wrong.

    I got drastic last night, backed up my libraries on an external and this morning am trying out RAID 0, and SHR-1 configurations. Nothing in Black Magic seems to get over 10-11 Mbps still, though sometimes gets up to 20 Mbps. But this is still way low. This can't be because it's the ARM processor in the DS-212j.

    I'm really not sure what to do next. My router is gigabit, my iMac definitely is, my cables are Cat 5e. I'm going to start exploring every piece of hardware starting with my Router and the Synology itself. Something's set wrong or broken.

    EDIT: I'm reading more and more that a router can be a bottleneck and that a Gb switch should be used to handle all LAN transfers. I guess I'll attempt this approach.

    Ok, I have figured out that my iMac is only connecting at 10/100 speeds. Checked Network Utility to confirm this. When I manually change the Hardware setting in the Network prefs I can't get an IP at all. Down the rabbit hole I go...
