March 10, 201412 yr I upgraded to 5.0.5 tonight and am noticing slower writes than I was getting on 4.7. Copying from Windows 7 I am used to getting around 30-35MB/s write speeds. It starts there but then falls to about 12 and doesn't come back up. Copying from the server seems to be OK. I'm getting around 75-90MB/s. These numbers are from TeraCopy. syslog03092014.zip
March 10, 201412 yr Attach a syslog that includes slow transfers. Note the time of the slow performance.

Do you use a cache drive to get these speeds (30-35MB/s)? I don't have that with my 4.7 (all my drives are green drives though)
March 11, 201412 yr Author Attach a syslog that includes slow transfers. Note the time of the slow performance. I'm not sure if this is helpful. I don't really see anything in the log but this Tower avahi-daemon[1334]: Invalid legacy unicast query packet. I started copying a 40gig folder around 10:24 and it is still copying. syslog-03-10-20142.zip
March 11, 201412 yr Author Show the output of "ethtool eth0" and "ifconfig". Dropped packets? syslog-03112014.zip
March 11, 201412 yr Sounds like a faulty CAT 6 cable, switch port, NIC, switch, router port, or router. Test and isolate. Start by connecting the server directly to the client. A standard CAT 6 cable will work, Gig-e does not require a cross-over.

A standard CAT 6 cable will work, Gig-e does not require a cross-over. I didn't do exactly as you said just because I didn't have time to move either machine. I did what I think is the next best thing. I tested the write speed to my Synology near the windows 7 PC. I then disconnected my Unraid server, moved the Synology to its spot and used the same network cable to plug into the Synology. Write speed in both settings was 50MB/s. Can I downgrade the server to 4.7 to retest? I have a copy of the old flash contents. I haven't made any drive changes.
March 12, 201412 yr Author Well that was a terrible idea so far. Super slow copies. ethtool revealed 10 MB link. I am tried swapping cables but now maybe the NIC is toast. No link lights. Edit: Rebooted server. Link lights are on, says link detected but can't get to it on network. Sent from my XT1053 using Tapatalk
March 12, 201412 yr Author Any ideas? It was lit up like a Christmas tree so I'm assuming it is doing a parity check. It has a link light, the router is blinking but I still can't ping it. Sent from my XT1053 using Tapatalk

March 12, 201412 yr Author ethtool said it had a link. I'll check it an post when I get home. Thanks. Sent from my XT1053 using Tapatalk
March 13, 201412 yr Author OK. So that went downhill fast but I think I recovered. I ended up recreating the 5.0.5 flash drive and making sure it booted, had network, etc. After that I copied my config in, checked the drives, and ran permissions. I'm still getting slower speeds than I recall in 4.7 and also way slower than the synology drive on the same cable. I understand it won't ever be as fast but it isn't even close and down from what I remember. Ultimately, I won't be able to readily replace every cable since one is an upstairs/downstairs run. Other ideas?
March 16, 201412 yr Author I don't have Cat6 or a long enough crossover so I tested a longer Cat5e cable and a new Cat5e cable with the router in between and then just a gigabit switch in between. I'm still seeing it fall to around 12-15 MB/s for writes. Again the same cabling got over 50MB/s writing to a synology setup. What is the average (not cache) for writes on 5.0.5?
March 16, 201412 yr I don't have Cat6 or a long enough crossoverGigabit automatically does crossover, it's no longer necessary to have a cable with the pairs swapped. What is the average (not cache) for writes on 5.0.5? Depends on the drives, connections, SATA interfaces, and the available CPU power.
March 16, 201412 yr Author Gigabit automatically does crossover, it's no longer necessary to have a cable with the pairs swapped. I'll try this again then. Depends on the drives, connections, SATA interfaces, and the available CPU power. I'm guessing nobody has noticed an appreciable difference from 4.7 to 5.x then?

Other ideas? Did you test the speed with the clean install? Before copying the the config?
March 18, 201412 yr Author Did you test the speed with the clean install? Before copying the the config? No. At the risk of completely proving my ignorance I didn't know that was an option. I thought the config told the array what drives were where? Should I try something like that now?
