Flash Performance issues - Macromedia Flash Player

There is a serious performance bug in flash player 9. The performance issues come to light when many web browser windows are open with a flash animation in them and the system slows down significantly. The reason for the performance issues is that Flash player is generating continuous page faults.

    Default Flash Performance issues

    There is a serious performance bug in flash player 9. The performance issues
    come to light when many web browser windows are open with a flash animation in
    them and the system slows down significantly.

    The reason for the performance issues is that Flash player is generating
    continuous page faults. For those who don't know what a page fault is; when a
    program needs to access an item from the system memory, sometimes the item
    doesn't exist in physical memory because it has been swapped out to virtual
    memory and is stored in a paging file on the hard disk. When this is the case
    a page fault occurs and the item is read from the paging file on the disk into
    physical memory. Each instance of flash player is generating between 80 and
    300 page faults per second, making very inefficient use of system resources and
    causing the system to be very sluggish when many flash animations are open.
    even the small flash advertisment on msn messenger generates 80 page
    faults/sec.

    The page fault usage can be observed in the Windows Task manager: click view
    menu -> select columns. Add the "PF delta" and the "Page Faults" Columns to
    the task manager and sort the list by PF delta. You will observe page faults
    occurring continuously in applications with flash.

    Its a pretty serious bug

    How much memory do you have? I now have 2 GB and I'm definitely seeing this behaviour. It's lessened but not absent if the window is in the background or minimised.

    I also have 2GB of memory - given the high amount of memory in our systems its
    hard to understand why a 30kb flash file should be constantly generating page
    faults. I'm not sure how to get around it but from what I can see it seems to
    only be the IE plug-in that is causing this, i'm not seeing this behaviour in
    firefox. I prefer to use IE7 but have been forced to use firefox because of
    this - in saying that I still think its an Adobe flash problem rather than an
    IE problem.

    Flash has gone to hell since Adobe took over. These memory bugs (see this one and another post on memory leaks) are serious performance issues.

    Wow, suprising to find this is the reason my Flash games have such odd
    performance behavior. I used to be able to account performance issues to number
    of objects ononscreen, long loops, etc. I was puzzled by the odd, seemingly
    random drops in performance with my recent projects. Now I can watch the number
    of page faults and see the correlation. This needs to be fixed ASAP.

    Thanks for the info, I thought it might have been some hardware issue I has having.

    Has this issue been addressed?

    It is seriously hindering my productivity developing on this platform.

    :o

    I didn't know about the page faults, but I do see numbers up till 1,500 in the
    page fault delta column for Internet Explorer.
    My computer consistently lags at certain points of flash games, but I have
    noticed that the Page Fault Delta numbers are always low/drop to a low # right
    when it lags.

    Never used to happen to my old computer.. which was pretty junk, and a Windows
    XP. Now I have this new vista and it's just giving me a ton of problems =[

    I dont know anything about computers but iam
    trying to run Adobe on Joel Osteen's website. And it just runs for a couple
    seconds and then stops and runs really slow. I dont think it has anything to do
    with my computer. It seems that its just not running fast enough. Kinda
    dispointing, i hope someone finds some answers to this problem.

    Do you have any advice? Flash player on Firefox seems orders of magnitude slower than on IE (6 or 7), and also much slower than Safari...

    Hello BWolfe,

    Any update on this issue?
    Will there be version 9 that will fix this issue?

    This is for us a critical issue, we develop flex applications (that are not
    very heavy) and as soon as the application is iconified almost all the memory
    goes from the Used Memory to the Virtual Memory => this memory is available to
    be swaped to the disk, then whenever (one or two) big application are launched
    the flash app is swapped to the disk (which is normal).

    The issues is that once you want to reuse your flash application, even if
    the big applications have been closed, you will have to wait tens of seconds to
    perform each actions, it's like if the application was frozen and you have to
    warm each part of it before being able to use it at it normal speed (which
    takes several minutes).

    I haven't tested yet to check if there is a similar issue using AIR but if
    that's the case then it should be a top priority for Adobe because I don't see
    how people will be able to sell application that freeze "randomly" from a
    user's perspective.

    PS : I am currently using the latest version of the flash player 9,0,115,0
    on windows XP and I have reproduced this issue on all the computer I have
    tested.

    best regards.

    Like pthomsen, I am amazed how Firefox cracks when there is a Flash. Sometimes
    I forgot a webpage with with a flash, and after a while my PC works very slow.
    At some sugestion from friends I upgrade to the latest but the problem
    continue.

    I do not have any updates on this issue. I do request that as many of you as possible open support cases via http://www.adobe.com/support (especially the flex developers).
