    Kaye, 3 items stick out:

    1) that your 2 x 150G Raptor striped startup is not on the built-in internal SATA bus but should be- I think it will be faster that way, too much contention with everything on PCI.

    2) the 64k block size for it; I think TZ tested and showed 64k was slower as a startup disk...32k was faster.

    3) test file on scratch disk- the 512MB will be faster with test file on striped startup, the larger test files, I'm not sure.

    The striped startup should be faster. I knocked off 6s with the test file on the internal SATA striped startup; scratch on external 4 x stripe.

    Lightbulb G5 2.7 PCI-X vs G5 Quad PCIe

    The Quad has better SATA support. Kaye can't use those Raptors on his internal bus.

    Booting from and using 4-6 drive RAID for both startup AND scratch or something, with test file present, of course?

    I thought that was only a problem with humungous single video files.

    As i understand it, those Raptors on the internal bus may not operate correctly as TZ says. Most likely not a problem at first but later on. Don't want to take a chance with that. Plus with what I would want on the Raptor RAID would put me at 54% full. I found no difference between 32KB or 64KB on the 2xRap150 startup disk.

    I can't imagine that 4 drives on one PCI-X card, 2 drives On the other PCI-X card, both on the 100MHz bus, would slow the system down. Should be way more bandwidth than 6 drives suck.

    Its academic anyway because I get the same results with my normal 500GB boot drive and 6xRap150 RAID. k

    Default A recap of stripe vs non-stripe startup with CS2

    Kaye, thanks for going through all this- at least we know what's what with the G5 Dual 2.7GHz/PS CS2/stripe or non-stripe startup. Sorry it didn't yield any benefit.

    ------

    I decided to verify my previous results regarding the startup disk as a striped volume or a standard volume with Photoshop CS2 (9.0.2).

    First I broke the 2 x 150G Raptor striped startup volume apart, cloned (from backup drive) back all files- except an image library- to a single standard DU volume 150G Raptor, then put the image library on the second 150G Raptor as a single standard DU volume, then repaired and optimized everything:

    Test platform: G5 Quad, 16GB RAM, nVidia 7800GTX 512MB GPU, Mac OS 10.4.9

    Two internal drives on built-in SATA bus, both 150G Raptors and both formatted as single 139.6GB volumes with Disk Utility:

    "Studio": startup with 118.4GB available, 21.26GB used.
    "Images": 117GB available, 22GB used.

    External RAID Array (ERA) scratch disk: 4 x Atlas 15K II SCSI drives formatted with SoftRAID 3.6 as a single 136.5GB RAID0 volume optimized as "Server" with 32k block size, 136.4GB available and 46.6MB used before use as scratch disk. These drives are connected to a UL5D in slot #4 using ATTO ExpressPCI4 4.0.0 driver and ATTO Configuration Tool 3.07 with default settings.

    ------

    I tested with PshopTest 2.1 and used a 30s pause for the 512MB testfile and a 45s pause for the 1.5GB testfile. Photoshop CS2 had the Bigger Tiles plugin enabled.

    9 test runs with the512MB testfile:

    1. 512MB TF, scratch on startup, testfile on Desktop, 70% (2150MB) memory, cache 6: 69s
    2. 512MB TF, scratch on startup, testfile on Desktop, 70% (2150MB) memory, cache 6: 75s
    3. 512MB TF, scratch on startup, testfile on Desktop, 70% (2150MB) memory, cache 6: 58s
    4. 512MB TF, scratch on startup, testfile on Desktop, 70% (2150MB) memory, cache 6: 81s
    5. 512MB TF, scratch on startup, testfile on Desktop, 70% (2150MB) memory, cache 6: 79s
    6. 512MB TF, scratch on startup, testfile on 2nd Raptor, 70% (2150MB) memory, cache 6: 58s
    7. 512MB TF, scratch on ERA, testfile on 2nd Raptor, 70% (2150MB) memory, cache 6: 57s
    8. 512MB TF, scratch on ERA, testfile on 2nd Raptor, 70% (2150MB) memory, cache 6: 58s
    9. 512MB TF, scratch on ERA, testfile on startup, 70% (2150MB) memory, cache 6: 58s

    2 test runs with the 1.5GB testfile:

    10. 1.5GB TF, scratch on ERA, testfile on 2nd Raptor, 100% (3072MB) memory, cache 6: 177s
    11. 1.5GB TF, scratch on ERA, testfile on 2nd Raptor, 100% (3072MB) memory, cache 6: 176s

    ------

    This all jives with my previous scores with the same config almost exactly.

    Here are my best scores accomplished with the 150G Raptors as a single 279GB striped volume. These were achieved in late January with 10.4.8:

    512MB TF: scratch on ERA, testfile on startup, 70% (2150MB) memory, cache 6: 53s

    1.5GB TF, scratch on ERA, testfile on startup, 100% (3072MB) memory, cache 6: 166s

    So the striped startup gain for me is 4s with the 512MB testfile, and 10s with the 1.5GB testfile.


    ------

    When I do eventually get an MP, I expect the fastest PS setup will be a multiple-drive striped startup coupled with a fast external array....

    My current fantasy Photoshop dream machine: 3GHz Mac Pro Quad (8 cores), 32GB RAM, 4 x 150G SATA II Raptor stripe + 4x Fujitsu SAS (150MB p/s each) as scratch. Ha!

    Renewed energy Boots after fixing my UPS problem yesterday by downloading and running the 10.4.9 Combo update PPC. That was my last resort, no utility would fix it nor downloading and applying the APC software again.

    Deleted the 10.4.9 boot 2xRap150 RAID with 64KB blocks then created a new Apple RAID with 32KB blocks. SuperDuper cloned my FW800 RAID with 10.4.9 to the 2xRap150 RAID with 32KB blocks. Checked it all out with utilities then shutdown so that I could shut off the FW800 RAID.

    Pshop Test 2.1, Cache Levels 6, G5, 10.4.9, boot volume 2xRap150 Apple RAID 32KB blocks, PS scratch only 4xRap150, SoftRAID 3.6, 32KB or 64KB SU. Photoshop CS2 v9.0.2. File now on boot 2xRap150 RAID, not on scratch RAID.

    Still no speed bump. And still the boot RAID does not seem to help. k

    Thanks Kaye.
    Well- the upside of all this anyway should be a healthy speed bump for PPC with PS CS3 when that arrives.

    For me, with the above test specs (2 x Raptor stripe startup, 70% memory)-

    the 512MB test file is 45s with CS3 Public Beta
    the 512MB test file is 53s with CS2

    For me, with the above test specs (2 x Raptor stripe startup, 100% memory)-

    the 1.5GB test file is 146s with CS3 Public Beta
    the 1.5GB test file is 166s with CS2 (best score)

    About a 15% speed bump in terms of PshopTest2.1 anyway...

    A 15% speed bump in PshopTest2.1 would certainly be welcome. For instance, the 3.0GB test I did yesterday, to get 581sec result took me 22min 41sec. k

    Default Speed Bump

    Based on what I learned from the previous test plus Boots' previous test post and TZ's comments and links, I decided to dump the 2xRaptor150 boot RAID and go back to my Maxtor 500GB-16MB cache drive for boot and create once again a 6xRaptor150 striped RAID with 32KB SU for both file and scratch. This turned out to result in a new level of performance results for the Pshop Test. I also tested the 10 drive RAID.

    Pshop Test 2.1, Cache Levels 6, G5, 10.4.9, 6xRaptor150 file and scratch, SoftRAID 3.6, 32KB SU. Photoshop CS2 v9.0.2.

    512MB file, Memory 70% 2150MB, 30sec, 6xRaptor150, 32KB SU, 64sec

    Previous 2.1 best, 10 drives, 128KB SU, 1780sec

    The 10 drive RAID does not provide a speed bump until somewhere between 3.0GB and 6.0GB file size but closer to 3.0GB. The 6xRaptor150 file and scratch really shows a bump for 3.0GB and 6.0 file sizes and this RAID is enough for me without the 10 drives.

    Out of curiosity I ran the 10 drive RAID at 32KB SU in QB3.1 to compare it with 128KB SU previously tested.

    100MB, 745MB/s read - 775 write - 128KB SU
    100MB, 641MB/s read - 787 write - 32KB SU k

    Nice Kaye- looks like you've eeked out pretty much the max acceleration.

    I discovered something nice today I hadn't known about: relocating Bridge's cache and 'use centralized cache..' for both images and RAW to the Atlas RAID speeds up the building thumbnails process in a huge way, and it also speeds up the Bridge screen redraw of folders with a large number of images after the thumbs are built. Sweet.

    I didn't know that Boots but I see how it's done. Even tho Bridge is of course on my G5, I have not used it since it first came out and was very buggy. I can see where your work would benefit greatly but my real work with Photoshop CS2 and ImageReady CS2 don't call for using Bridge as far as I can tell, unless you feel differently about that or can tell me how I would benefit. Always open to your expertise. k

    I use Bridge as my primary "digital asset manager". It's pretty handy when you've got multiple versions of images, and need to flag stuff to compare and create collections of images for web etc.

    Since my image archive is big (20G) and organized in numerous subfolders, Bridge makes it a snap to quickly find stuff.

    For CS2, it's up to 1.0.4 and is pretty stable on PPC at this point; 10.4.9 gave it a speed boost too.

    More learning. Added 2 more Raptor150 drives. This turned out to result in a new level of performance results for the large file (3.0GB and 6.0GB) Pshop Test. And because of the volume size,1.090TB, once running out of real RAM (8GB), plenty more breathing room for virtual RAM and Cache Levels 6 on the 8xRaptor150's. Adding the 4x15K2 drives for a 12 drive RAID hurt by comparison because the volume size reduced to 409.4GB.

    Kaye, when you receive CS3- in addition to enabling the Bigger Tiles plugin, you'll want to test using perhaps two additional performance plugins.

    I don't know whether Adobe has left VM buffering disabled or enabled it like with CS2. If disabled by default, there should be a plugin called something like "Enable VM Buffering". If not, it's probably already enabled by default. In any case you'll be able to tell pretty quickly when testing a large file size.

    The other one should be especially useful with your monster fast scratch disk-
    it's a plugin called "Disable Scratch Compression".

    I'm not certain if the final release contains these plugins on the cd/download, or whether you'll need to download them separately.
