Jun 22, 2016 6:08 AM in response to Tom521by BobHarris,I actually had a longer reply, but the forum lost it on me
Thank you for actually providing some information that can be worked with.
There is a specific FCP-X forum. I suggest you post your questions about FCP-X there, as it is less likely this specific thread will be a good place to address that.
Since you have a Drobo 5N, why not try using iSCSI which will totally bypass any 10.11.5 SMB security changes. iSCSI drivers are installed as part of the Drobo Dashboard. iSCSI is 1-to-1, so you cannot share the storage with other computers, but is very efficient for storage access.
You should check with Drobo to see if they have any firmware updates. Also Drobo has their own forum where it is possible you are not the only one experiencing this issue, so that might be a Drobo specific place to find help.
You might try booting into Safe Mode (as an experiment) to see if some 3rd party software is interfering

This is strictly a diagnostic, not a solution.
You might try installing the 10.11.5 Combo update. Sometimes, basically reapplying all the .1 .2 .3 .4 .5 updates addresses issues that creep in
<Download OS X El Capitan 10.11.5 Combo Update>
This edited reply is less than what I originally wrote.

According to the Drobo web site the 5N does not support iSCSI.
I looked at the Drobo site, and already have the latest firmware and Drobo Dashboard.
I downloaded and installed the OSX El Capitan 10.11.5 Combo update. No noticeable improvement.
I will try the safe mode boot next

Jun 22, 2016 9:11 AM in response to Tom521by Tom521,Bob,
The safe mode boot gave the same results as the normal boot, i.e., about 1/2 the pre-OSX 10.11.5 rate. Still too slow to be usable.
I checked both the AFP and SMB mount protocols under safe mode - same result for each - using BlackMagic speed test. Less than 90mbs declining to less than 70mbps over several test cycles.
Any other thoughts?

Jun 22, 2016 9:22 AM in response to Tom521by Bill Scott,One possible workaround is one I use with my NAS (a freeNAS-based system), that seems to work better (I have not measured speeds, so this is somewhat subjective), is OSXFUSE with SSHFS. Briefly, it uses ssh to establish the connection (I use a public/private key pair). I realize this doesn't address the problem, but it is so simple and seamless that it might be worth considering as an alternative to downgrading the OS.
Edit: this bb software is incredibly buggy. I wonder if there is an SMB file share associated ...

Jun 23, 2016 6:53 AM in response to Bill Scottby Tom521,Bill, I downloaded OSXFUSE and got rid of MacFUSE. Couldn't figure out how to implement OSXFUSE. Maybe I'm just dense... Bob, Ran Onyx again and cleared out all the caches, deadwood etc. New behavior: The three stick figures no longer show up - the icon for the mounted Drobo starts off as a black Drobo and stays that way. Checking info reveals the connection is still SMB. Alas, no speed improvement. Tom -
Jun 29, 2016 12:53 PM in response to Samplexby Tony_YYZ,Has anyone tested to see if OSX 10.11.6 has fixed this incredibly annoying issue? I don't have a spare machine to test with.

Jul 3, 2016 11:00 PM in response to Samplexby Theo-T,Latest thing I have tried is to add client_signing=no to etc/snmb.conf but no luck, I have had this issue for year(s), and it just can not work.
I have moved stuff now via FTP by using third party software.
Hopefully this gets fixed soon, I think this should be pretty high in priority, I understand slow development in months but years are too much to fix such issue...

Jul 3, 2016 11:56 PM in response to Theo-Tby Theo-T,I have now also signing_required=no there but no luck
4.51GT (119k files), takes approx 4days, I think its not normal in gigabit local network, right ?
-
Jul 4, 2016 7:18 AM in response to Theo-Tby Seth Goldin,The file you need to create is named nsmb.conf, not snmb.conf.
Also, the flag is signing_required=no. This was a typo in the original post. See here: Re: Re: Re: Re: El Capitan 10.11.5 update SMB slow (bug)

Jul 4, 2016 7:33 AM in response to Samplexby VikingOSX,El Capitan will autosense the version of SMB presented to it, and prefers to do SMB3. If your maximum SMB version to use in the Synology DSM management software is still configured to SMB1 or SMB2, that may introduce the bottleneck you describe. You will likely need to reboot the Synology after these File Service changes. Stay on top of your DSM updates as they continually introduce performance and compatility fixes.

Jul 18, 2016 11:35 AM in response to VikingOSXby Samplex,10.11.6 also didnt fix the slow transfers rate!

Jul 18, 2016 11:49 AM in response to Samplexby Seth Goldin,Samplex,
I haven't updated yet. I've been holding off in case there were other huge issues like this one.
Was your global nsmb.conf file preserved, or did you have to recreate it? Were speeds OK once you had the signing_required=no flag back into your global nsmb.conf file?

Jul 19, 2016 5:47 AM in response to Samplexby SagarMCP,the 10.11.6 does have some fix for the SMB network shares its worth trying the upgrade. I will update sometime today and will post how it goes.
-
Jul 21, 2016 12:27 AM in response to Samplexby SagarMCP,10.11.6 also not fixed this issue. not sure how to get this raised to APPLE.
during one of the support calls root user account login managed to fix it.
-
Jul 21, 2016 5:26 AM in response to SagarMCPby Tom521,Wow! I just updated to 10.11.6 - the Drobo got waaaaay slower, as in 15mbps instead of 70 which was the slow speed for 10.11.5
Now the NAS is truly useless. Pity. Apple is worse than the Windows world now. First, crashes. Now slower than molasses.
Question: could you post the detail for the root user account login? I will certainly try it if you will.
Tom
