Fodder Posted August 9, 2012 Share Posted August 9, 2012 Hi Guys, I have been running Unraid 5beta 12 since it came out, with no real compalints, until now. And to be honest it has me stumped, the transfer rates on my system have dropped through the floor. the only thing I have done to the system (only today) is enable NTP to fix the time reporting and the slow down predates this. other than that it works so i leave it alone. Capacity is 60% on one drive and 70% on the other. I have read "to cache drive or not to cache drive" and several other threads but i cant seem to find a reason for the slowdown. I cant give you any "before" figures as i didnt bother to take any "it just worked" But now i cant stream a movie with out chopping etc. The server is a simple one PRO -licence 1 x 2tb parity drive 2 x 2tb data drives 1 x 500gb cache drive. Intel PCIE1gb nic card I run UNMENU and Simple features, plus the monthly parity check script. to give you some perspective: If i copy a 700mb video file FROM the server to my laptop (connected via a 1GB switch) i get 9.5MBs using terra copy if i write a file to the array i get 6MBs (to the share, so via the cache drive) If i move a file internally (using Putty and then MC) i get 30MBs I also ran "TOP" while copying the file from the box and the most it got to was 3% cpu and mem was the same. Idle there is nothing taking CPU or RAM in amounts of 1% UNMENU DISK SPEED TEST REUSLTS /dev/sda: (Parity drive) Timing cached reads: 1840 MB in 2.00 seconds = 920.15 MB/sec Timing buffered disk reads: 346 MB in 3.02 seconds = 114.68 MB/sec /dev/sdb: (Data Disk 1) Timing cached reads: 1954 MB in 2.00 seconds = 976.75 MB/sec Timing buffered disk reads: 326 MB in 3.01 seconds = 108.34 MB/sec /dev/sdc: (Data Disk 2) Timing cached reads: 1954 MB in 2.00 seconds = 977.38 MB/sec Timing buffered disk reads: 406 MB in 3.00 seconds = 135.17 MB/sec /dev/sdd: (Cache drive) Timing cached reads: 1944 MB in 2.00 seconds = 972.03 MB/sec Timing buffered disk reads: 250 MB in 3.01 seconds = 83.12 MB/sec /dev/sde: (flash/boot drive) Timing cached reads: 1850 MB in 2.00 seconds = 925.37 MB/sec Timing buffered disk reads: 48 MB in 3.11 seconds = 15.44 MB/sec Below are the vital details of the box plus some of the things asked for in other threads.

JonathanM Posted August 9, 2012 Share Posted August 9, 2012 I have been running Unraid 5beta 12 since it came out, with no real compalints, until now. And to be honest it has me stumped, the transfer rates on my system have dropped through the floor. Have you tested multiple client machines? Have you checked the network speed of the client machine? It almost looks like you are connected wirelessly instead of wired. Quote Link to comment
Fodder Posted August 9, 2012 Author Share Posted August 9, 2012 Hi Jonathanm, Thanks for taking the time to respond! Actually i tested the READ from the server with TerraCopy both wired and wireless, and the wireless was 8MBs. But i can understand why you would ask that! I have just done the following test with TerraCopy Laptop (wired) from tower 9.5MBs Media center (wired) from tower jumping around between 9.5 - 30MB/s laptop to media center 10MB/s So the laptop is a problem, will have to address that, but it still does not explain the transfer rates from the Array to the media center dropping off enough for TerraCopy to display a speed change down to 9.5. (it drops down to 9.5 for about 30 seconds) I will go out and get some new CAT6 cables and install them tonight a see what i get. Any other ideas? Are there any other reports i can run after a copy from the media center (connection that is intermittent ) that will give us some more info? (just so we are clear my current network is all hardwired and is running Gigabit switches. I have wireless but i am hardwired for this, and wireless is disabled on the laptop.) Again thanks for your time. Quote Link to comment
Fodder Posted August 9, 2012 Author Share Posted August 9, 2012 I just realised that this is in the wrong section, sorry! Mods please feel free to move it. Quote Link to comment
JonathanM Posted August 9, 2012 Share Posted August 9, 2012 I have just done the following test with TerraCopy Laptop (wired) from tower 9.5MBs Media center (wired) from tower jumping around between 9.5 - 30MB/s laptop to media center 10MB/s Can you try a different gigabit switch? As another test, you could assign a static IP to both the laptop and the server, and connect directly from the laptop to the server without the switch. It really sounds like you have a network problem, I don't think the server has anything to do with it. Quote Link to comment
Fodder Posted August 10, 2012 Author Share Posted August 10, 2012 ok, I brought home a better GB switch from work for the weekend, i will try that in there. then i will try replacing the old network leads with new ones and see what i get. Also another thing i should have mentioned at the start the server has a static IP. thanks! Quote Link to comment

Also another thing i should have mentioned at the start the server has a static IP. thanks! Since the server already has a static IP, set your laptop to a static IP as well, and plug the network cable directly from the server to the laptop and run some transfers. Quote Link to comment
Fodder Posted August 11, 2012 Author Share Posted August 11, 2012 Ok, Here is the setup. Media-PC - static IP UNRaid Tower - static IP WD Mybook (eth connect version) - dymaic IP Laptop - static IP GB Ethernet switch in media closet GB Ethernet Switch in Study Internet provider modem Cisco EP3925 (gig eth port connected to switch in media closet I tried all the tests below with new cables and on each switch/router to see is something was broken Nothing was different from switch to switch/router The file i used was a 6GB mkv movies file. to narrow down the list of the culprits i first used a WD MYbook (it is the one with a Ethernet on it) from the WDMYBOOK copied using TerraCopy, to the Media-PC 30-32MB/s - Verify of that same file with TC ran at 46MB/s to the laptop 5.8MB/s (with static IP same) I then copied the file to the WDMYBOOK from the Media-PC only getting 17-19MB/s and verify at 13MB/s so, I then copied the same file (but the one on the UNRaid box) From the UNRaid tower /SHARE/ to the laptop 8-9.5MB/s From the UNRaid tower /DISK/ to the laptop same. From the UnRaid tower /SHARE/ to the Media-PC 35-40MB/s From the UNRaid tower /Disk/ to the Media-PC same Getting a little frustrated at this point as the problem has disappeared, so i put back everything EXACTLY as it was (ok, i am coming out. I have a label-er and i like it! everything gets labeled!) Try and recreate the problem and its back up to 30-40MB/s. Now any sane person would quit while they were ahead and go grab a coldie and watch the olympics, but nooooo, no me. I pulled it all apart again and started over. New CAT6 cables all over, neatly tied up and separated from power. The wife thought i had gone mad, muttering to myself and throwing cables over my shoulder as i disassembled the media closet. What do i get for my efforts, other than a nice neat media closet (which is kinda cool on it own) ZIP! So is 30-40MB/s read speed acceptable, i am l thinking not. Quote Link to comment
redbeard Posted August 13, 2012 Share Posted August 13, 2012 Almost sounds like a machine is running not on gigE but 100mb connection - which would max out 12-13. Other machines seem to do gigE speeds. Quote Link to comment
Bungy Posted August 14, 2012 Share Posted August 14, 2012 It's unclear how you are copying the files to each computer. Are you physically going to each computer and copying the file over to it or using one computer as a pass through? Also, which file transfer protocol are you using for each test machine?
