Mac OS X incredible slow on network drives??

    Hello all,

    I post this in the Mac Basics and Help. I am pretty sure that this is just some setting somewhere that needs to be set. Otherwise it would be too crazy.

    Now networking is pretty popular these days, better backup possibilities and off cause much more space.

    I only have 250GB's in my Mac.

    When I work with pictures from cameras I save them in folders on a network drive for others to use as well. It is a windows network but that should not make any different? Why on earth is the Mac so slow? Just showing the thumbnails in one single folder takes for ever? One of the folders contains about 200 images, so it isn't even that crazy? When I try to open or even just copy one single image it takes forever? I have to use my windows machine to see which pictures to open so I don’t have to waste minutes opening the wrong ones.

    What can I do? I can't possible be the only one with these problems?

    Thanks in advance,

    Lars Petersen

    I have the same problems... I was told to use something called Bandwidth Optimizer but all that did was speed up my Internet Browsing to a small degree.

    Could someone possibly have a real fix? I do not know.. but don't listen to those who think the problem is related to tweaking your MTU settings.

    How is the Mac networked to the windows box?

    Is the networked drive formatted in Fat 32 or NTFS file format

    If the networked drive on the windows box is NTFS then Macs Can't write to the drive only read to the drive

    It is a normal windows network. Windows server 2003, filesystem is NTFS, as it would typically be in 90% of all normal networks, i can read and write just as a Windows computer, the real differents is the speed. It is so slow that it is almost useless. I can't really believe the Mac's are best at working locally?

    Are you connected to the shared volumes via SMB?

    I haven't really tested SMB speeds, but it wouldn't surprise me one bit that SMB on Mac OS X is pretty slow.....

    No problems with AFP though. Maybe you try a test using AFP sharing?

    My home directory at work is an automouted SMB drive. It's lightning fast. I get 2-3 MB/s connecting to it via the network.

    The file format shouldn't matter if it's shared properly.

    The format doesn't matter if it's a network drive, OS X isn't writing directly to the disk, the server is.

    Mine is automounted SMB drives/folders as well. How strange? Can I turn some settings off perhaps? Maybe there are some settings which uses a lot of bandwidth? Or maybe I need to do something special on the server?

    Just dragging one image from the network folder on to my desktop on the Mac makes the cursor think in about 30 seconds, then i can release the button and copy the image. First it calculates how long time it will take to copy the image (for one image??), and about 1 minute later it is done. And this is just one single image at 3-4 mb's.

    Any possibility of getting those SMB shares to be AFP shares?

    Like I said before, I have not done any SMB speed-tests, but I am confident AFP does't have those speed issues you guys have.

    There's definitely something wrong and it should be fixable. I'm not sure how, though, since I have experienced it myself on occasion.

    Have you searched Apple's support forums? I'm sure there has to be some article there if this is a common problem.

    Is your Mac OS X install up to date?

    I think I remember something about the way different API's size the chunks of data for writing files...IIRC the carbon file routines write in very small chunks which means that when your send say 8 kb every time (just example), the routines have to wait until the server has confirmed its stored the 8 kb completely, so if your sending a 128 kb file, it has to wait 16 times for the server to reply its actually written the chunk. IIRC other APIs send using larger chunks, so its faster using a network because it doesn't need to wait for so many replies from the server, but the carbon routine may be faster in local storage (again this is AFIAK, I may be wrong...).

    To confirm this, try to copy a file using the finder, then copy the same file using the terminal using cp. See if there is any difference....

    Duh - Don't think so !

    This is NOT true - it would be true if the hard drive was physically connected to your Mac, but it is not, the server reads and writes to the Hard drive and not your Mac ! - It is SLOOOOOW sometimes, I tend to use AFP where possible rather than SMB (Samba) shares - this does tend to speed things up a lot !
