    Moving media files on Unity is slow

    Moving media within same workspace is slow.

    I have seen this before on several systems, and wondering if anyone has a solution.  System setup is Unity Server MN 5.1.3 16TB media engine.  Clients are connected via fiber working on a MacPro 12 core 2.66ghz with OS 10.6.8 and MN 5.5.1 client software.  I have tried using MN 5.2 and 5.3.3 all with same problem.  When I try and move media files from a folder roughly containting 5,000 files to another folder within the same workspace it takes extremely long(30 minutes or longer)  I am not copying files, just moving them.  I try grabing smaller number of files at a time, which seems to help slightly.  Seems like the finder is trying to index all of the files constantly. 

    If I map network drives on the unity and follow the same process, the procedure is instant.  However this shouldn't be a problem from the client system.

     

    Thanks for any information.

    Re: Moving media files on Unity is slow

    We're running an old LANSHARE EX3 with the 4.2.4 software, and we have also found that moving/copying files onto the Unity has always been really slow. However - we're all Ethernet clients, not fibre.

    I'm sure one of the Unity gurus will be able to answer better - but I assume the slow copying is because of the way the Unity processes the Metadata - and also the fact that (in our case anyway) all the workspaces are protected, so the Unity has to think about two files instead of one (which is done in software, not hardware I believe).

    It may seem crazy - but sometimes we'll just plug a USB drive into the LANSHARE directly to copy files to the Unity, as it's faster than copying over the network!

    That said though - once the files are on there, the Unity is quick as a whip, and more than capable of juggling multiple edit suites and large quantities of footage - and our little LANSHARE is definitely getting on in years.

    I'm betting you answered your own question here.  Make sure Spotlight is configured to IGNORE network attached drives and Unity Workspaces.  then you might find this works much better.

    Re: Moving media files on Unity is slow

    After testing further on several different systems (unity and isis) I have seen a common problem with managing files on the finder level.  Especially with opening OMFI media file folders, the system is extremely slow.  Avid posted the following in regards to finder level copying on Macs.

    This still seems like a major issue and I am surprised that I have not seen more post reffering to this issue.

    Re: Moving media files on Unity is slow

    Thanks for sharing the link! I've never seen that article before.

    I'm going to do some speed comparisions between ARR Sync and just using Finder.

    I'm also going to do some tests between copying a folder and copying the contents of a folder.

    Surely there must be a solution on the developers end to this? Every NAS and SAN in the world must have to deal with the same issue of a seperate Resource & Data Folk - so I'm sure there's a solution.

    I'm actually very surprised that the ISIS you tested had the same issue.

    Have you been testing with Fibre or only 1GbE?

    We have a Force10 25P switch with 10G uplink.  The client systems are all connected via fiber.  The client systems running os 10.6.8 are extremely slow, and I am going to test systems running 10.7.2 to see if there is a difference.

    TravisB and Chris Hocking,  Have you done these tests yet? I'm curious what you've learned.

    Re: Moving media files on Unity is slow

    Unfortunately I continue to have slow finder level issues.  The workaround I have done is to use a windows cpu for finder level migrations.  Not always possible, but on bigger projects it saves us a lot of time and frustration.
