Re: ReadyNASOS 6.4.1-T29 (Beta 2) : RN104 drops out when writing files
Since I updated to this software version ( ReadyNASOS 6.4.1-T29 (Beta 2)) I have noticed that I still get occasional drop outs when listing large directories in SMB mode. Also SMB is much slower than it used to be. I use this machine as back up and it seem to take twice as long to back up my files.
Actually times are quite inconsistent. I jut backed up two directories separately and one of 7GB took 20 mins and on on 14GB took 8 mins.

I've seen a drop in SMB speeds on my RN102 also, but not as much as you are seeing. Read speeds have dropped more than write. I used to see ~50 MB/s write and ~70 MB/s read. Now I'm seeing about ~45 MB/s in both directions. Both of your backup speeds are quite a bit slower than that. Lots of small files take longer with SMB than fewer large files. Is that possibly part of the explanation?
NasTester is a convenient way to test throughput (http://www.808.dk/?code-csharp-nas-performance). You could try using that, and posting the results here.

Thanks Stephen, Here are the results. One thing the results don't show is how long it took to execute the warm up. It seems as if the NAS has gone to sleep and needs a while to wake up as it seems to take a long time before copying even begins.

I'm not certain what NAStester is doing during the warmup, but it does take a while.
Your read results are similar to what I am seeing on my RN102 with 6.4.1-RC3.. But your write speeds are slower than mine (and more variable).
Do you have antivirus enabled? How about IPv6?

Re: ReadyNASOS 6.4.1-T29 (Beta 2) : RN104 drops out when writing files
I do have antivirus enabled.
As to IPv6 I do have that on my PC but I don't know if its on the ReadyNAS. How can I check?

ipv6 is configured in the network settings page (click in the settings wheel, there is a "general", IPv4, and IPv6 tab).
Try disabling both AV and IPv6, and measure the speed again.

Re: ReadyNASOS 6.4.1-T29 (Beta 2) : RN104 drops out when writing files
I can't see those choices.
Am I looking at the wrong page?
Under System, Settings I see: Services, Update, Configuration Backup, Alerts and Support.
Oh I found it now the popup was't working on the network card cog icon earlier but It works after I rebooted my NAS box.

Re: ReadyNASOS 6.4.1-T29 (Beta 2) : RN104 drops out when writing files
That was bit of a nightmare!
After changing those settings the NAS crashed repeatedly for around an hour, only staying up for a few seconds each time. Now it seems to be stable again.
Here are the test results:

Hopefully someone from Netgear will take a look at the gui error.
The write speed is somewhat better, and of course the NAS should have stayed stable.
Are you running production 6.4.1?

Re: ReadyNASOS 6.4.1-T29 (Beta 2) : RN104 drops out when writing files
The stats above were done on T29.
I have now upgraded to production 6.4.1 and it seems to crash whenever I try to use SMB. T29 was a little less crash prone. Now I can't complete a run the NAS test software.
I'm now saving up for 12GB of disk so I can make a backup and start again. 😞

Re: ReadyNASOS 6.4.1-T29 (Beta 2) : RN104 drops out when writing files
The write pattern of NAS Performance Tester (NASTester) appears to cause the Anti-Virus scanner to misbehave, and eat up gobs of CPU and RAM. The system does not crash, but it appears unresponsive for some time until the kernel eventually kills the AV scanner as part of its OOM handling.
So, you probably want to disable Anti-Virus before running this.
