    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    Going back a bit here my Raid O set was created in Leopard and my X-Bench score are 211 now and they used to be 239. I'm questioning the Raid set being done in Leopard now and maybe untangle them and redo them in Snow instead. I got a weird feeling. I have my usually experts on it now for advice Bob, Jack and Lloyd.

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    A number of folks are reporting lower XBench scores, which may be an artifact of the weighting that XBench uses or perhaps something peculiar about the benchmark itself.
    Many users are attributing this lower score to dramatically lower OpenGL numbers.

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    Xbench is just a reference, it only is useful when using the same version of the OS. Even then it's not necessarily a completely accurate representation of actual speed.

    This anomaly used to happen with MacBench many years ago under OS 9 as well.

    In my former life as a hardware developer for Macs (CPU upgrades) I found nothing worked better than real-life speed tests. Those tests are dependent on what the primary application the computer is used for. In our field since we were focused on CPUs we used CPU intensive software (complicated Photoshop actions, After Effects, etc.) Since we tested in the same exact system and simply swapped CPUs, the hard drive, memory and video all remained the same and the only variation were the CPU(s) themselves.

    In this case since the hardware remains unchanged and only the OS changed, I'd still recommend using real apps for speed tests. But unless those tests were done under Leopard first, before installing Snow, it's too late (unless one has multiple identical boot drives, one with Leopard and one with Snow.)

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    Synthetic benchmarks are pretty meaningless.
    We used to even write compilers to detect certain of them and emit special code.
    Better to use a real application realistically to make a more meaningful measurement.
    OTOH, sometimes they are of forensic value to pinpoint an anomaly.

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    I guess you guys are right I am suspecting X bench to not be very accurate to begin with. Let me time a c1 conversion maybe that will give me a clue

    Just ran some actions in PS with Open Gl on and it went very fast and C1 was on target as well.

    Just opened a 194 mg file in a spilt second in Preview and also tried it to open in Safari . Okay they are both 64 bit and fast as hell. Need to try this. Just right click on a image and open in preview

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    FTR, Xbench is reporting a 20 pt. performance drop on my Mac Pro as well. I suspect that Xbench will need an update to be able to more accurately gauge 64-bit performance.

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    TIP:

    There seems to be some confusion about 32 vs. 64 and which macs can or can't. I found this little bit of shareware that might prove handy for those of us less tech savvy than some. It will tell you whether your mac is capable of 64 and if so, whether it's currently booting into 64 or 32. Plus, it allows you to select which mode you want to boot into. When you restart it will confirm the change when you open it again. Pretty nifty little control.

    Also, it might bear repeating that to boot into 64 you can do the same thing by simply holding down the 6 and 4 keys on startup (or the 3 and 2 keys).

    Carlos love ya and thanks for that. But being the guinea pig i am and just to make sure our members know all the ins and outs. The idiot here is untangling my Raid O from leopard which is a question mark and redoing it in Snow Leopard but at least i can clean my drives off which honestly may have something lingering like stinky feet. Than I will install the DVD OS back on the main Raid O volume . Than from there I will migrate from my current Snow Leopard backup. This maybe a complete waste of time and effort and may proof absolutely nothing but I got a bug up my you know what and i can go to sleep at night knowing I did about as clean a install as possibly human. Which means nothing to anyone but I can get it off my mind. Than I can tell all of you to just upgrade with confidence. Someone has to step in the pig crap to make others smell better.

    As long as we're at it, let's clear up any potential confusion (which I haven't been seeing here, but HAVE seen in other places) about "64 is better than 32 because it's more, and more is better."

    Here's what Apple says on this topic:

    For many developers, however, compiling their code into 64-bit programs may not offer any inherent advantages. Unless your program needs more than 4 GB of addressable memory, supporting 64-bit pointers may only reduce the performance of your application.
    This quote came from a blog post by Adobe's John Nack, titled "A 64-Bit Reality Check" (you have to scroll down a bit to read it.) It also includes a link to the original Apple document that includes a "common misconceptions" section.

    Reading these may help with any impatience people may be feeling for "Why hasn't my developer issued a 64-bit version of _______ yet?"

    Eventually, 64-bit will be a good thing because it will enable developers to release applications that can address huge amounts of memory, which is generally a handy thing for image-processing applications.

    Until then, it's likely that most of the speed benefit many of us are seeing from Snow Leopard is because of the cleaned-up, more-tightly-optimized code... which will benefit 32-bit as well as 64-bit apps.

    No real X-bench change but it feels faster . Go figure , just upgrade

    A clean car has significantly lower aerodynamic drag. May not make a tangible difference unless you do most of your driving on the Bonneville Salt Flats, though.

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    Okay I have everything working and almost all my software back. Two little programs I use Fetch is not ready and Letterbox for mail is not ready . Other than that one glitch in C1 and that is the progress bar separates but it is faster to process even without new 64 bit code. One program I had to install Rosetta was Eye One 3.6.1 needed Rosetta and also on boot the reminder to calibrate come up every time. Dowloaded 3.6.2 and that reminder went away but it still says PowerPC so you can instal without Rosetta and if it needs it than it will go out and get it on the internet and download. These are the little nits and nothing major.

    I do have one Major issue and that is the e-sata express card I have a Caldigit adapter card. At first my drives would not show up, went to download there driver and got them back up. This is not a Snow Leopard driver yet but booting normally I have them up. Now try booting in 64 Bit and I lose those drives. So just waiting for a new driver to be able to do that.

    Other than that I am actually pleased with it, it is snappier and of course that is hard to tell on my machine since I am running SSD in Raid O. But we have to remember who this upgrade is really for and it is not the end user but for developers to be able to write code better and faster to market, plus it makes the machine more bullet proof. For a photographer exactly what we want. It will get much better obviously as code is written for 64 bit.

    BTW Helicon focus is 64 bit and it fly's. I hear Lightroom and Aperture are running very well indeed under it. Just waiting for C1 update for myself and I will be happy happy happy. It's hard going to a completely all laptop machine for someone that shoots high end digital with big files so speed is critical to keep up. End of the day this looks to be a winner in the end

    Guy, please keep us updated on the Caldigit esata. We're running a FW800 drive until the issue is resolved.

    I will Bill . You have a Raid box it sounds like which one do you have.

    I will send them a note today and see what is up

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    There appears to be more to the story. There is an article on today's Luminous Landscape about Snow Leopard and Epson printers.

    http://www.luminous-landscape.com/essays/woes.shtml

    As an Imageprint user with an Epson 3800 I'm sitting tight for a while...

    Re: Snow Leopard : Tips, tricks and whatever else we need to know

    Wish I could say the same for Canon. I called imagePROGRAF support and their answer was: "Don't upgrade to Snow Leopard until we release the drivers and we don't know when that will happen."

    They also informed me that current printers will be released first, then older models like my W6400 later.

    I found a workaround that does the job quite admirably: Parallels 4 + Win7 + Qimage. Far less expensive than any RIP solutions that work natively on the Mac and if I spring for the Studio version of Qimage, I get multi-core support. This configuration is supported by Qimage, BTW.

    Re: Snow Leopard : ImagePrint 7

    For the record.

    ImagePrint 7 is supposed to be compatible with Snow Leopard but needs to be updated by downloading latest version from Colorbyte and uninstalling the old version & reinstalling the newest version. (New Epson Drivers should also be installed...)

    I haven't done it yet but reportedly it works fine.

    See: http://tech.groups.yahoo.com/group/I...ew/message/120

    I'll report back if I experience any issues...

    Update:

    For what it's worth...

    I did the deed when I could afford my system to be down for a while.

    Interestingly. Epson has links to Snow Leopard compatible drivers for my Epson 4800 on their website but these links take you to older drivers that are listed as only compatible up to OSX 10.5.x. (!#@%&)

    After loading Snow leopard & discovering that my PCIe SATA Card Driver from Silicon Image was causing a Kernel Panic (Fixed with an updated driver), I then wasted a few hours trying to find a current Epson 4800 Driver. No luck but after installing Rosetta, I just reloaded the old Drivers which works fine so far. Reloading Imageprint had a few hiccups but was up and running fairly quickly too. So in the end, this upgrade was relatively painless compared to the many Windows upgrades I have done in the past. LR 2.6 still seems slow but the a little faster than before with better memory handling.

    So if anyone is interested...Snow Leopard, Imageprint 7 and the Epsoin 4800 can "play nice" together.
