I do believe there is an inherent bug somewhere that possibly does not like my hardware. I've been using unraid since the beginning of V5 or even before that. When V6 first came out things were good. After a couple of revisions is when these copying issues started. I always would get 100MB/sec on copy speeds using a Windows workstation on the network and even faster using the terminal and midnight commander. My server box is a simple norco 4224 box. I have a 1000 watt power supply which has been replaced. The cables that go from the backplane to the controller cards have been replaced with new ones. I've changed the memory out temporarily with a friend's memory. I've disabled the on-board NIC and purchased an Intel add on card. I've re-seated the processor and ran extensive tests on the processor itself. The mainboard is an Asus X79 that has tried different bioses. I've tried different controllers. Dell PERC 310's and/or the SuperMicro SAS2LP-MV8. I have like 4 of each of these cards. Tried them together and in different combinations. If I did not have so much data, I'd try to go back to V5 and see what performance I would get. Since the copying of files issues happens via the terminal this eliminates pretty much anything outside the server box. I've even taken the mainboard out of the server box and installed it in a small desktop case and threw Windows 10 on it. Problem free. And while I had Windows 10 on it, I ran several heavy duty burn-in test programs just for the heck of it. Flawless. Reinstalled the board back into the 4224 box, booted up just fine. I've also moved my pro key to a new USB flash stick that was vanilla. No plugins installed, plain vanilla. Tried changing some bios settings, but really not that many. I basically turned off all VM related stuff and tried different settings with that.
In a nutshell when copying files the system would start to copy just fine around 80-100MB/sec. Then eventually slowly drop down to 0MB/sec and the copy would literally stop completely for about 30-40 seconds. So if I'm copying a large amount of data it could take days to do this. ( Yes, the parity drive has been replaced ) . Takes about 2.5 minutes to copy a 6GB file when it would take seconds before. I don't even attempt to copy amounts of data anymore and I also think this issue is affecting my system as a whole. Specially when watching a movie. During the entire movie it would freeze ( which is where it stops ) then picks up again and the movie catches up again with the player. This happens with my Dune players AND my Roku players.
Another oddity I did a parity sync which took 2 hours ( great! ) but the average speed indicates 1.1GB/sec. Is that even possible? Attached a screen shot of that and diagnostics. I'm pretty much lost from here. I did attach a terminal copy that looks very weird, but you'll get the gist of what is happening once you see it. It is just one 6GB file being copied.
Any suggestions or recommendations is highly appreciated.
Thanks
