troubleshooting: RN316 very slow to view directories of files

Question

To be frank; i've been using the home NAS for quite a few years and its basically a data storage box which backs up my files and media files for streaming.&nbsp;Works well for these sceniarios, however when i do try to connect to the NAS via AFP (via my MBPs) it is a dog to wait for the directories and files to load. I am not talking about 1-3 seconds, i am talking about up to 30seconds at times.&nbsp;See picture.(#1) on initial connection to the share file, this folder appears in 1-2sec(#2) has approx 50 files/ folders - takes 5-10+ sec(#3) Digging into level 3 - it can take 7-10+ sec(#4) Digging into level 4 (approx 110 files) - can take 30+ seconds to load?The rest is the actual utilisation of the readynas webview UI. Very little chatter on network (2 users)&nbsp;As mentioned, i've used this to sync with BTSync (Resilio) and/ or dropbox as backup drive, then use offsite backup. Thus i really don't have a need to 'browse' through these directories from the NAS, i'd love to, however due to above issue, i never do...&nbsp;The RN316 is 6bays with 4,2,2,4,2,2TB in RAID6 configuration and going through wireless - Netgear D8500 Nighthawk X8 AC5300.Not too sure what is causing this?[edit] - i have antivirus on NAS turned on,&nbsp;- turned that off, no real noticable diffeference- MBP CPU utilisation is at approx 3%&nbsp;Questions:1. Any tips to help troubleshoot this or find the root cause?2. Would it make a REAL difference if i move from RAID6 to RAID10 (i googled this - however would be a project just for migration)&nbsp;Note: When using synchronisation tools such as Bit Torrent Sync (Resilio) or&nbsp;sychronising files across the LAN, i can still get speeds up to 25-40MB/s and this may include syncing lots (i mean hundred of thousands small files) at any time and or large movie video files.TIA

What firmware is the NAS running?
&nbsp;
Are you trying the directory browsing test over ethernet or over wifi?

jamminontoast · Answer

Firmware is 6.9.1 (generally i update to the latest when told)

Browsing the directory is via WIFI...

i have 'invested' in the latest WIFI tech so i would have 'hope' that at least get a decent speed, even if my MBPs (2014) it uses "802.11ac Wi-Fi wireless networking; IEEE 802.11a/b/g/n compatible" - however that browsing directory speed is very poor....

I'd prefer NEVER to cable my apartment.

Tried switching off anti-virus. Don't know if taking on the mamoth task to change from RAID6 to RAID10 will make any substantial difference in this regard...

Understood, but doing a test with ethernet is the best way to rule out the wifi network.&nbsp; &nbsp;One big issue (especially in an apartment building) is WiFi interference from your neighbors - who are sharing the same radio spectrum you are using.&nbsp; Also there can be interference from microwave ovens, nearby elevators, etc.

I don't think it will.&nbsp; One thing that will help is using the new SSD metadata tiering feature.&nbsp; That requires at least on free slot in the NAS for the SSD.

Thanks guys: the router is wired to the NAS, however the computers are all wireless. The MBP are generally&nbsp;~16ft away&nbsp;- clear signal directly without walls or interference.&nbsp;i followed your suggestions&nbsp;and there are some other thoughts.1. Using the&nbsp;cable, i get somewhat (random?) responses. Some folders will pull up&nbsp;from 0- 3 seconds. Then i may decide to back out to the root and it takes 10s to open another.&nbsp; i've loaded what my screen looks like here: http://bit.ly/2DDvjNX &lt; apologies for the flickering...2. Using my User account on MY owned 2x MBPs.... (2013 and latest MBP 2017) - same results.3.&nbsp;Using a different user on a different MBP (same specs as mine) - they have no problems . Most folders pull up in 0-3 seconds.4. Using my User account on the OTHER 2x MBPs.... the speed&nbsp;is&nbsp;relatively normal again... even browsing through folders with 100's of sub folders.&nbsp;This looks to be a 'user' aka. (ME!!) error some where... both MY MBPs have been refreshed earlier with High Sierra along with the other MBPs.&nbsp;So i am baffled at why this is the case...- 1. the only difference between my workstation and my partner's workstation is probably the amount of software i have on mine. Though most are shut off and spun up when required.- 2. the other difference is that i have about 8 different share folders whereas i limit my partners to 2. Most of my shares are software documentation folders which runs into the (300GB + and millions of files). However the testing (as per the video) is done against our media drive.&nbsp;i am competely lost.... ;(&nbsp;[edit] - i've been reading up on RAID10 recently and should of went with that RAID setup instead of 6.... had done a few resyncs as of late and the speed does suck on transfers... anywhere from 1- 20MB/s transfer depending on size of files.

i will also add to this, i was previously using PATHFINDER software, which also allowed me to see invisible files - it took the mac/ or network extra processing time... though i switch completely to finder and results are not much better (a little bit).&nbsp;Though my partner's machines, work fine...&nbsp; using the same software is fine!&nbsp; &gt;stumped&lt;
