Very slow copy with SMB
Hello,
I have very slow copy with SMB since 6.9.0 : 9 Mo/s. Normaly it's 90-100 Mo/s
Tested without SM3 Encryption. It's the same.
Anyone can't help me. Someone have the same problem. Can y...
Just to say the encryption on SMB3 is to difficult for ARM on RN102 and that why SMB use all the CPU ressource with very slow copy.
for me it does not help. I turned off SMB3 encryption. Client PC is Windows 7 Pro x64.
I make new backup Job. Files in job are copied OK. but then job is In progress forever and does not stop. It happens on my RN104 and RN204. Tried from 2 different windows 7 PC. the same.
For RN204

For RN104:

i tried restart outh NAS units, router, switches... nothing help.
No difference if client PC is Windows 7 or Windows 10.
Files are copied, jobs hangs at "In progres"...
So it looks like the RN204 speeds have dropped about 10 MB/sec over what you reported here: https://community.netgear.com/t5/New-to-ReadyNAS/Transfer-speed-on-rn204/m-p/1027539/highlight/true#M9719 I wouldn't call that "very slow", but it is a noticable drop.
Do you know what the RN104 was giving you before?
Also, has anything changed on your network since your earlier report?
>>>May i ask what is your client OS?
My PCs are all Windows-10 now. My windows application server and my RN52x NAS use 10gbaseT, which is of course a lot faster than gigabit.
I installed FW 6.8.1 to my RN204 (RN104 is FW 6.9.0 for test)
run SMB job and gues what? It works on TF 6.8.1:
Backup Job Name: UT Backup Backup Job Type: Incremental Protocol: cifs Backup Source: [remote:cifs]///192.168.77.100/uTorrent Backup Destination: [Backup]/uTorrent Backup Start Time: Tue Oct 24 2017 20:43:54 Backup Finish Time: Tue Oct 24 2017 20:43:55 Backup Status: Success
This is RN204 back on FW 6.8.1:

Iteration 1: 87,07 MB/sec Iteration 2: 84,19 MB/sec Iteration 3: 74,79 MB/sec Iteration 4: 76,45 MB/sec Iteration 5: 82,10 MB/sec ----------------------------- Average (W): 80,92 MB/sec ----------------------------- Running a 400MB file read on \\pmnas02\transfer 5 times...

So your issue is just with the backup job, not with SMB generally?
I think that it is something on FW 6.9.0. Because AFTER install FW 6.9.0 ALL SMB backup jobs does not end correctly. Old or new created. When i downgrade one unit to FW 6.8.1 all jobs on downgraded unit are OK.
Jobs on another unit (RN104 FW6.9.0) still hang after copy all files on status "in progres" and does not end at all. Jobs for rsync work OK on both units.
For me it seems that there is something in FW 6.9.0 causing problem.
It makes no difference if client PC is Windows 10, Windows 7, Windows 2003 server.
no difference if job is new created or old one from earlier FW.
Only think that makes difference is using FW 6.8.1 instead of FW 6.9.0.
RN104 and RN204 was configured independently. But on Both is problem after upgrade to FW 6.9.0. So i thing that is not some "problem on config" on both unit.

I was asking if you are seeing issues with SMB in 6.9.0 in normal use (that is, not in the backup jobs).
No problems with SMB. Speed seems to be OK for both units.
Problem is with backup jobs using SMB only.
(i'm not sure what is oroblem in the job, because i tried to control speed of copy (by time) for jobs and it seem that fires are copied about thes same speeed on both FW 6.8.1 and 6.9.0. It seem that thjere is some problem in next phase in job (after copying files). I dont know how to call that. Som it may be that SMB protocol is OK, but job is doing something wrong?
