    Hi Ben,

    I have used SR 3, when analysing the trafic with BigTop I have found curious behaviors. So I trash it !

    Can you run BigTop with SR 4 to see if it is still happening and send me the disk I/O diagram at cb dot pub at numericable dot com

    YOU MUST use last version of VI PRO and VE PRO so I can compare (VSL has divide the loading time by 40 with my raid of SSD)

    FYI : You can use a Raid 0 for your lib, and back them up on a single disk

             more you have disk in a raid 0 faster it is

    Best

    Hi Cyril

    Sure I'll try Big Top - although I have never heard of it until now. I am in geeky mood so I'd like to try.

    By the way, SoftRAID is verison 4 now - which is multithreaded and has other advances included SSD support.

    I'll get back to you. What was the curious behaviour you had? Just so I know what to look for..

    Thanks

    Can't find Big Top. Do you have a link to it?

    To have it you need to install the developer package on main OS X DVD

    Set the analysis time to what needed. to have the graphic of the disk load during loading the VE pro server 64 bit

    The behavior is difficult to explain with my knowledge of English

    Ok I will do that. I'm on a dealine for some days so it may have to wait...

    In the meantime, if I observe Activity Monitor, I see that Disk Activity only exhibits a maximum of about 25MB/s. This seems really strange! I wonder if VEPro is being held up looking at the licence dongle or something.

    Is this with the latest version of VI PRO and VE PRO server 64 bit 7846 ?

    Yes - 7846, 64bit, OSX 10.6.6, latest eLiscence software.

    I think it's time to raise a support ticket.

    1. VI (and VI embedded in VEPro) uses single threaded loading.

    2. VIPro uses multithreaded background loading. The number of loading threads are the same as the number of cores available in the system.

    3. We do not write anything to the disk during loading.

    Thus, if Softraid works as you say, you should experience a higher loading speed with VIPro. 25MB/sec sounds like a normal figure with a single, non-raided modern (spinning wheel) drive. The figure you want to look at regarding disk performance with our instruments, is the "64k Random read" value.

    Thanks,

    Thanks MS. Really useful information. I am building a strategy based on your advice now.

    The key lesson here is seek times are king.

    Did you made the Diagram with BigTop
  • B

    I will. as I say I have some deadlines.

    However, I've gone ahead with SSD disks already. Totally different speeds. The information from Martin, however, implies that it doesn't really matter what the throughput speed of a drive is - seek times are what holds up the load. Thousands upon thousands of 64k files - perfect for SSD!

    I will get around to testing though - it may be in a couple of weeks though.

    You just need to load Bigtop set it to see 600 or more secs and you load your orchestral template
