My RN102 is painfully slow

Question

Hi everyone,&nbsp;I’ve had some difficulties using my RN102 for a long time. Transfer rates are actually more or less ok, but it’s the access times (right-click, access folders, copying a file…) that are painfuly slow. In those times of confinement, it’s been really hard to work using my NAS here.I’ve always liked PCs and enjoy to assemble my machines BUT concerning networks, I’m just a newbie, honestly 😊. Let me try to describe my config first :&nbsp;I’m using two WD Red (3 Tb) in RAID 1 mode (with 1Tb available). I do not use any app on the. The NAS is connected to a small D-link hub, along my internet box. The hub is directly linked to my PC. I run Win 7 pro 64bits on my computer (runs particularly fine). Sometimes I plug my old XP notebook onto this network. I encounter the same problems listed below on both computers. To put it bluntly, I don't think I'm asking much here, I just want to keep it simple, with a fast and secure access to my files.&nbsp;I’ve partitioned my NAS in 3 virtual drives :Drive A : Pleeeenty of files, images, pdf, etc. That constitutes my “personaly library”. Due to the recurring slowness above mentioned, I took the habit of accessing it as little as possible, in the hope of better days to come (Unfolding all the directories on windows explorer and/or displaying picture previews is sooooooo slow).Drive B : My personal photos. I moved the most recent ones on a local drive, since it tended to be damn too slow to work with Lightroom. In terms of fluidity and accessing files, it’s the same problem thanin A..Drive C : All my music. It’s ok here, I can listen to it on winamp (I know, I like it old) BUT when I encounter accessing problems, it can stop.&nbsp;While recurring, all these problems are not systematic. Sometimes it works ok, and for the past 48 hours for instance it’s been damn slow just to do a right click on some files or document (as if I was asking windows to check files miles away using a 56k modem). What is certain is that I never enjoyed the fluidity and immediacy of the Qnap NAS we’re using at work for instance (and believe me, the whole installation is quite peacemeal over there).&nbsp;On my NAS admin page, everything appears to be ok (but as I said, I’m really not a pro here). I tried to stop the antivirus (but did not notice anything conclusive). Is the RAID-1 the reason of all this ? Am I missing something here ?&nbsp;I’d be tremendously grateful for your help ! Any tip is warmly welcome. Please do not hesitate to ask me any details if need be, I’d be glad to provide it.&nbsp;Thanks again, pardon my rusty English, and cheers to all the confined people of the world 😉Guillaume

&nbsp;

If you still have antivirus option, then you are running old software (it was removed from the RN100 series a while ago, because the NAS no longer has enough memory for it).
&nbsp;
What firmware are you running?
&nbsp;

No.&nbsp; But it would be good to look at the disk health.&nbsp; Try downloading the log zip file from the logs page in the web ui.&nbsp; Take a look at at the smart stats in disk_info.log.&nbsp; If you don't know how to interpret them, you can post them here (either as a pdf attachment, or cut/pasting them into the reply).
&nbsp;
Also, have you ever run a btrfs balance or a scrub?

Can you check the ethernet speed on the network page of the NAS, and let us know what you are running?&nbsp; Perhaps also check this on the PC.

Hi Stephen, and thank you for your quick feedback !

_You're right about the antivirus, I did not even notice but it's gone from the UI. I just remember I had a big issue with it a few years ago, but anyway.

_I'm running with 6.10.3 (and am up to date, apparently)

_I'm afraid I never consulted the logs (I don't know how to handle these). Here's a screenshot of what I get when I download them all, anything specific you want me to upload ?

_I programmed a scrub (ie a "cleaning" right ? Not a defrag ? I have a French UI, just to make sure we understand each other ;)) every monday. I just realized it's still running right now :smileyfrustrated: Would it be the cause of my problem ?

_I could try the balance, you're right. Each and everytime I want to balance or test, it takes so much time I just forget it...

_On the network page, I have a bandwidth of 1Gb/sec (Network card is Qualcomm Atheros PCI-E, part of my Asus F2A85-V). Speaking of that, is there any way I can test/map my whole home network, so that I can determine where is located the flaw ?

Thanks again

&nbsp;

Open disk_info.log in notepad.&nbsp; Then you can post the info here (as suggested above).&nbsp; Best to copy/paste into your reply (not a screenshot).
&nbsp;
You could also search system.log for btrfs errors (just search for btrfs).

&nbsp;

Scrub isn't a defrag, it does other stuff.&nbsp; It will slow down performance when it is running (as will the balance).

&nbsp;

If the balance always takes a long time, then you probably need to run them more often.&nbsp; Scrubs generally take about the same amount of time, but the balance will run quite quickly if there isn't anything it needs to do.

&nbsp;

One aspect here is that SMB isn't very efficient at folder browsing (and that appears to be the performance issue that bothers you the most).&nbsp; So if there are a lot of files in your folders, you might need to re-organize them into subfolders, which would help.
&nbsp;
But first we should rule out the network and the NAS itself.&nbsp; You can test with NAStester, it would give us some better idea of the large file speeds you are seeing.&nbsp;&nbsp;http://www.808.dk/?code-csharp-nas-performance&nbsp;

Here's the data from disk_info.log :Device: sdaController: 0Channel: 0Model: WDC WD30EFRX-68EUZN0Serial: WD-WMC4N2537953Firmware: 80.00A80WClass: SATARPM: 5400Sectors: 5860533168Pool: dataPoolType: RAID 1PoolState: 1PoolHostId: e35da80Health dataATA Error Count: 0Reallocated Sectors: 0Reallocation Events: 0Spin Retry Count: 0Current Pending Sector Count: 0Uncorrectable Sector Count: 0Temperature: 31Start/Stop Count: 416Power-On Hours: 44047Power Cycle Count: 416Load Cycle Count: 365Device: sdbController: 0Channel: 1Model: WDC WD30EFRX-68EUZN0Serial: WD-WCC4N1LF9UVXFirmware: 82.00A82WClass: SATARPM: 5400Sectors: 5860533168Pool: dataPoolType: RAID 1PoolState: 1PoolHostId: e35da80Health dataATA Error Count: 0Reallocated Sectors: 0Reallocation Events: 0Spin Retry Count: 0Current Pending Sector Count: 0Uncorrectable Sector Count: 0Temperature: 31Start/Stop Count: 384Power-On Hours: 29376Power Cycle Count: 384Load Cycle Count: 457There appears to be no btrfs errors on system.logI downloaded and ran NAS perf tester. I got an average speed of 10mb/sec (write) and 7,50mb/sec(read).Then I stopped the scrub operation that has been running for two days on my NAS, ran NAS-PT again,and got 31,8Mb/sec (write) and22,5mb/sec (read).Of course, the scrub process was slowing it all (I feel a little dumb now :smileytongue:). Ioriginally configured it so that it runs when I'm away at work, but now I'm locked down at home,I'm much more on my PC (and totally forgot to disable it).So, according to the data I posted, is everything back to normal ?
