My RN102 is painfully slow
Hi everyone, 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 ...

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).
What firmware are you running?

No. But it would be good to look at the disk health. Try downloading the log zip file from the logs page in the web ui. Take a look at at the smart stats in disk_info.log. 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).
Also, have you ever run a btrfs balance or a scrub?

The NAS is connected to a small D-link hub, along my internet box. The hub is directly linked to my PC.
Can you check the ethernet speed on the network page of the NAS, and let us know what you are running? 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

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

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

If the balance always takes a long time, then you probably need to run them more often. 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.

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). So if there are a lot of files in your folders, you might need to re-organize them into subfolders, which would help.
But first we should rule out the network and the NAS itself. You can test with NAStester, it would give us some better idea of the large file speeds you are seeing. http://www.808.dk/?code-csharp-nas-performance
