    Internal RAID causes interface lag

    Ever since moving my sound and music libraries over to my internal RAID, I've noticed that MC lags horribly. I click on a bin, wait a couple of seconds, then it highlights. I hit PLAY, wait a couple of seconds, it plays.

    As soon as I rename the "Avid MediaFiles" folder so Avid doesn't see it, the lag disappears. 

    I currently have 112 folders inside of "Avid MediaFiles," and I've made sure that none of them have more than 5000 files in them. 

    Is there a way to have a lot of media on a RAID without slowing down the application?

    112 folders?

    Thats a lot.

    I have a software RAID 0 with 2xWD 2T each.

    I dont have lags ever but the 112 folders could be a problem.

    How many T's is your RAID? IS it 0?

    Re: Internal RAID causes interface lag

    RAID5. 20TB. 

    Hardware RAID with an LSI card.

    I definitely saw a difference when I went from 5 folders to 100. But the whole reason I got the RAID was so I could have all of my media in one place. There must be something I can do to remedy this.

    Re: Internal RAID causes interface lag

    One thing you might want to try is to turn off disk indexing for this RAID.

    In case you don't know how to do this...

    1) Right-click on drive and select properties.

    2) Uncheck the box that says "Allow files on this drive to have contents indexed.......

    3) Pop-up dialogue appears - click on "apply changes to subfolders and files.

    4) click OK

    Your PC will now run through all the files switching off drive indexing. Since you have a lot of files on your RAID, this might take a while!

    Trying this now! Thank you for the suggestion. Will report back with results.

    Re: Internal RAID causes interface lag

    I got several 30TB arrays going on an LSI adapters, everythings as smooth as silk.

     

    anything odd in the raid manager or event log?

    Re: Internal RAID causes interface lag

    I think I just discovered what the problem was. 

    In my MXF folder there was a ".bg_1" folder that contained files from a failed background transcode. Once I moved those files into their own numbered folder and deleted .bg_1, the app started to behave normally again! Unreal. I've been trying to figure this out for weeks. 

    Now, I've noticed in my MEGARaid Controller software that my LSI chip is running hot. Might need to access to bios to turn up the fan speed.

    Re: Internal RAID causes interface lag

    cool bananas.

     

    I'd solve the heat issue by pointing an additional 8 or 9cm fan direcly at the raid card.

    just let the fan sit on the bottom of the case.

    Re: Internal RAID causes interface lag

    I was wrong. I hadn't moved my Avid MediaFiles folder back into place after I deleted the bg_1 folder, so I fooled myself into thinking it was fixed. 

    Back to square one. 

    ____

     

    I started adding 1 folder at a time into my MXF folder just to see how many folders it could take before Media Composer started to slow down.

    I noticed lag between 30-40 folders. 

    I don't know if that means anything. Open to any more ideas. 

    Thanks.

    Re: Internal RAID causes interface lag

    I don't suppose this lag could be because my Raid is RAID 5 instead of RAID 0?

    Re: Internal RAID causes interface lag

    I've got the exact same problem now.

    after updating from 6.5 to 8.4.4 including OS reinstall

    MC hangs for a second about every fourth time i hit playback.

    no problem with a few MFX folders, but with many.

    Disabling windows drive indexing didn't help.

    msm re-Indexing everything didn't help.

    Disabling AMA Management didn't help.

    It's not the Mojo Hardware

    swapping lo end guadro with hi end GTX didn't help.

    I'ts not the Raid.

    It's not MCState or Site or User Settings

    same problem with MC 8.4

    It's not Fast Scrub

    Play Length Toggle has no effect

    Installed 8.4 on the largely identical backup machine (same chipset board, same ram, cpu, raid card, drives, different gpu that i also tried in the affected system):

    no lag looking at the exact same 20TB of MXF Files.

     

    The only idiosyncrasy of the affected system that i can think of, is that it's fresh win 7 SP1 w/o updates (cause the don't work yet (balls). since OP has win10, common cause seems unlikely.

     

    rather misterious

    Re: Internal RAID causes interface lag

    Lukas, how big is your RAID? What are your system specs? How many folders in your MXF directory?

    Re: Internal RAID causes interface lag

    On a side note, using RAID5 with big drives (bigger than 2TB) is asking for trouble, as there's a fair chance you'll run into a read error while rebuilding. This will make you lose all your data.

    Just use RAID10.

    my mirrored raid 5 arrays beat your single raid 10 in data safety, speed and reach price parity at high capacity ;)

    I've run through this exact same troubleshooting and had no luck. 

    Thank you for sharing. I suspect this is a bug in MC v8. We just need to get Avid developers to take notice!
