Slow share performance on my RN 104 since upgrading to 6.4.0
I upgraded to 6.4.0 two days ago, obviously now wishing I'd checked the forums first as my ReadyNAS was running fine on 6.2.5, but didn't think they'd send out such a poor release.
Anyhow, I've searched round and found plenty of other people with issues with 6.4.0 but none of the scenarios identified apply to me (I do not use jumbo frames (it's always been 1500), my ReadyNAS is not periodically locking up, I do not and never have had disc spin-down enabled, and although I did have IPv6 enabled, when I disabled it and rebooted it made no difference) so thought I would start a new thread in the hopes of getting some ideas / assistance.
For me it's just slow at file operations. Half the speed it was before the update, running at about 27MB/s when doing a file copy on Windows from my PC to the ReadyNAS using SMB shares. This is a pain, but what is worse is that it's broken my workflow in that part of what I do many times a day is uncompress ZIP and RAR files which are between 1 and 3 GB each to various shares on the ReadyNAS for colleagues to use. This doesn't work any more. Anything more than about 800MB or so and the uncompress will fail with "network name is no longer available" type errors. Uncompressing the file to my desktop and moving it to the share works fine (if substantially slower than before).
The UI itself doesn't seem any slower.
Any ideas anyone?

I am seeing similar speeds with the RN102 running 6.4.1. (generally mid-30 MB/s on large file transfers).
Right, and you agree / think that that is below par, right? That is - it was running faster before the upgrade to the 6.4.x software? I was getting 50-60 MB/s consistently (my PC has gigabit, and only has a GS308 between it and the ReadyNAS, not that anything has changed there between before and after the update).
6.4.1-T35 is faster, but still there seems to be a dropoff.

Diwakar: I looked in to downgrading back to 6.2.5 too, as I thought that might at least get me back to the kinds of functionality I was used to, but from what I have been able to find, it's a bit fiddly and means that you have to find somewhere else to put all your data, as one of the steps is a factory default. As I have coming up for 5TB of data, I don't have anywhere I could store that while I did the reset, no to mention the sheer amount of time it would take to copy all that data off, and then back on once I did the reset.
Ack, I spoke too soon about my ReadyNAS not locking up.
I was copying a file to it just now, and the copy failed. Can't connect to the shares now, nor the web UI, the LCD doesn't come on if I press the power button, and even if I hold down the power button, the unit doesn't shut down.
This is a terrible user experience and is definitely making me regret recommending ReadyNAS to family and friends; I hope they don't experience similar problems and I'm certainly not recommending it any further until Netgear can at least hold their hands up and say "yes, there's a problem, and yes we're working on it, hold tight, sorry".
I fixed the problem for me now.
The Downgrade worked for me.
Backup all data, Downgrade to 6.40. beta 1 ( hXXp://www.readynas.com/download/beta/readynasos/6.4.0/ReadyNASOS-6.4.0-T112-x86_64.img )
and Then downgrade to 6.2.X, then factory reset
thank you all.
My problems are all fixed now. I'll never run any update so quickly again. Never touch a running system.
My DVBLINK and OwnCloud app is working fine now, too.
+1 for seeing issues with poor transfer performance since upgrade to 6.4.0 (most noticeable on my RN312 - I don't have a RN104, but thought it worth me adding my experineces to this post). Sometimes connection just drops on my Gb LAN with my Win7 clients using SMB, causing copy fails. Not in a business critical environment, but annoying (and surprising) just the same. Hoping the next release will sort the issue....; )
Thanks, JohnNulty, I agree - it seems like too much of a coincidence not to be related.
joel80: I'm pleased that that worked for you, but it's really not an option for me. It would take 4-5 days to copy the data off, then do the reset and another 2-3 days to copy the data back on, and that would be after I spent £150 on external drives, and accepted no data protection for a week, hoping not to lose anything.
For me, that's not a solution but as I say I'm glad it was for you.
Netgear really need to be the ones to resolve this, or at least provide an alternate path back to 6.2.5 that can be done in-place, if they don't intend on fixing the problem.
Two more hangs today. Not yet gotten to the end of resyncing the data as it's unresponsive each time and I have to power cycle.
Don't know what to do. Some comment / help from Netgear would be appreciated at this time.
Hello TheGMan,
Can you try changing the MTU to 1500? Or if it is already 1500, change it to 9000 then change it back to 1500.
Regards,
Tried this - but wish I had not! No improvement in performance but totally screwed up my iscsi setup. Could not disconect in win7 (to reboot the NAS). Had to restore to the day before and set MTU back to 1500 to be able to connect to the LUN again.
Upgraded to 6.4.1 RC1.
Don't see any difference - share performance is still at between 15 and 25 MB/s.
I only upgraded last night (after it spent 4 days resyncing data after a crash) so I don't know if it's more stable and not crashing yet.
- The support team are not being very supportive about this issue!
Hi StormUK,
Could you PM me the case number?
Kind regards,

You're all complaining about the performance of 6.4.0. Well, 6.4.1 is even worse! Opening a small Excell file takes me about 12 minutes. I'm afraid to save the file to the NAS. It's better to save files locally, put them in the cloud using something like dropbox and putting them back on my NAS when Netgear has come up with working firmware or I have bought another, for instance one made by Synology.
I contacted support after 6 days of trouble. It took about an hour and in the end there wasn't any improvement. It could be, so they suggested, that the new firmware had some trouble resyncing and loading, it just needed a lot of time and I should give it some more time.
Then I just got this brilliant idea. Why not try to reinstall firmware 6.4.1 again, manually, over the installed 6.4.1. So I did and left it overnight. This morning my ReadyNAS performed like there was never any issue!
So to others having trouble: download the firmware found in Support / Downloads and just reinstall it manually. It might help you as it did for me.
Hello RobTwo,
Thank you for sharing.
We appreciate your contribution to the community. Engineering is already aware of the slow performance problem with the 6.4.1 version and they are already working on it.
Regards,
We eventually resolved the problem we had on our two NAS's by downgrading to 6.2.5, this has to be done by booting from a USB stick and then Factory Resetting the units.
Just really annoyed that Netgear didnt suggest this a month ago as this problem they created with 6.4.0 has cost me days in time.
