How to reduce memory footprint

Hello, while I observed that Audition always loads whole audio document into memory, I'm having quite a problem when processing long multichannel audio files as the whole physical memory gets utilized instantly I'm getting exhaustive disk swapping. This is especially awkward for long operations. I'm having a question if there's a way to reduce the memory footprint, ie. to Audition loads into memory just the file part that it's just working with, or to turn off undo. I assume the rapid memory usage is caused by collecting undo data also, whose I don't need in most cases.

You can use the Clear History button in the History page to clear all undo data or selectively clear individual steps from History.

  • How to reduce memory usage?

    OK - I've read through a ton of posts that discuss the "Out of memory" problem in Encore, but what can I do to reduce memory usage?
    I'm trying to produce a very simple Blu-Ray (h.264) project in Encore CS3 on Windows Vista. There are 8 or 9 timelines, a main menu, and 6 sub-menus. Each sub-menu has six static buttons. There are no transitons or motion menus. When I load the project, Task Manager says Encore is using about 1.3 GB RAM. I constantly get "out of memory" errors.
    I've loaded the same project on Vista 32-bit w/ 4GB RAM and Vista 64-bit w/ 8 GB RAM. Same behavior on both.
    Two questions:
    1. Why does Encore need 1.3 GB RAM for such a simple project?
    2. How do I reduce the memory usage?
    TIA for help on the PITA,
    rgames

    Please check with below link, if this can help.

  • Large image sequences in Flash - How to reduce memory usage?

    So I'm trying to publish a looping animation in Flash with a large amount of image sequences in it. (around 3000 frames all told). And I'm having problems with the swf using too much memory when it's played.
    The swf is about 80mb, but the file uses an excess of 2gb of ram when played. I don't know why that would be. A memory leak?
    My understanding is: that Flash will just load all images in a swf into memory unless you dump the memory somehow.Can anyone explain how to do this? Is it possible? I can't seem to find a solution online.
    Thanks

    Thanks for your reply. I think I was being just overly ambitious trying to get this to play in swf form on sub 4gb ram machines. I've resorted to external video.

  • How to reduce memory usage when loading bitmaps from the library?

    When I use BitmapData.loadBitmap() to load an image from the library and then attachBitmap() to add it to a MovieClip it takes a lot more memory as opposed to just having the same image inside a MovieClip statically in a frame on it's timeline.
    The function dispose() not only clears the BitmapData object but also destroys the previously attached bitmap inside the MovieClip, so it can not be used to free any memory.
    Is it how it is supposed to be or is there any other way to dynamically attach bitmaps with memory usage comparable to just having them on stage?

    no, you use attachMovie() to create instance from library movieclips that have a linkage id.
    you can then create a bitmapdata instance and use the draw() method to overlay as many as needed.

  • Reduce SQLDeveloper memory footprint with JDK 1.7

    Hi!
    Some time ago in another thread (Re: Memory problems with Oracle sql developer there was a suggestion to try the new Garbage-First Garbage Collector. which should be production in JDK 1.7.
    I use SQLDeveloper with JDK 1.7 on 64bit Linux with good results:
    - everything feels faster, snappier
    - fonts rendering is different, but it is OK
    - the bugs noted in other threads are not a showstopper for me (the connections pane not showing up on startup, not being able to scroll more than 1 OCI array size of records in results grid)
    In the above mentioned thread there is a suggestion that the new garbage collector should improve memory footprint of SQLDeveloper, however, this is not my experience, since it behaves pretty much the same as with JDK 1.6 (resident size between 700 and 900 MB).
    Do I need to use these opotions (as per reffering thread) to enable the new garbage collector (see below) or is it switched on by default in JDK 1.7? The reduced memory footprint would be very welcomed, because I use Oracle Warehouse Builder at the same time (also a java app) and there is always much pressure on memory.

    Thanx

    Hi Aleksander,
    Glad to hear of your good report on Java 7's HotSpot VM regarding performance -- it has various enhancements, of which the new garbage collector is just one. In terms of interpreting memory footprints, take a look at:
    http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html#generation_sizing
    Note the diagram indicates total heap size does not include the permanent generation memory. Xmx limits the heap size (the young and tenured generation). MaxPermSize limits class and method metadata plus static variable content. (Apparently starting back in Java 5 there are even some cases where the permanent generation space can be shared by multiple VM instances to improve start-up time and reduce memory usage.) These two limits control distinct, non-overlapping areas of memory.
    When monitoring a Java application's heap consumption with a profiling tool, I doubt the reported usage will exceed the Xmx limit by much. Monitoring with Windows Task Manager, however, can be a bit misleading. I have read several critiques in years past on how Task Manager reports program memory consumption. "Mem Usage" is actually the working set size. "VM Size" is program private memory rather than the true virtual size. And who knows how it tracks the Java VM's permanent generation size. Will it depend on whether it is shared or not?
    So I cannot really recommend any additional parameters to you. Just trust in the Xmx setting and hope that SQL Developer keeps any memory leaks to a minimum.
    Hope this helps,
    Gary

  • Reducing JVM memory footprint

    I want to deploy what may turn out to be a JavaSpaces application on some Windows PC clients. These clients will receive event notifications from a central server and then pop up a GUI for the user to respond to. These clients may be memory-limited and am worried about deploying a J2SE runtime purely for this application and eating up 30+Mb of RAM.
    J2ME runtime seemed like it offered hope as regards reducing memory footprint but doesn't really seem aimed at a standard PC.
    Does anyone have any advice as to which direction I should go in as regards JRE ?
    Gary Roussak

    I haven't checked into it thoroughly, but I've heard repeatedly that 1.4 has a smaller ram footprint. It is still in beta, so that may not be the way you want to go, but you still may want to look into it.

    Not all of the virtual memory assigned to a process is a problem - you need to look at the amount of memory that is commited (i.e. consumes pages of RAM and/or disk) to the process and not shared with other processes. Furthermore, the working set (the memory that has been recently accessed and needs to be in memory to avoid thrashing) is often much smaller than that.
    You can substantially reduce the private memory needed by the JVM by minimizing the heap size (-Xmx and -Xms parameters) - I've been able to run real programs accessing databases in as little as 2MB of heap.

  • I'm on iTunes 11.0.0.63 for Windows. iTunes used to display the total number of songs in my library, along with total playtime and memory footprint, at the bottom of the window. How can I make it display this information like it used to?

    Hello! Thanks in advance for reading my question.
    so, I updated iTunes to 11.0.0.63 on Windows, and the new layout looks nice, but iTunes no longer gives my total song count, memory footprint, and total play-time at the bottom of the window, the way it used to. I just want to know how to get that info back. Thanks so much!

    Ctrl / or View > Show Status Bar should do it.
    Weirdly having turned mine on the menu is not there to hide it again and the shortcut doesn't work.

  • How to minimize OC4J memory footprint?

    We use Oracle 9iAS R2 on a Windows 2K server with dual Xenons and 2 GB physical RAM as an integration server. There the various developers all have differenct OC4Js set up for testing. Now an Oracle rep once told us that many OC4Js within an iAS instance are no big deal because an OC4J had a memory footprint of about 3 MB RAM.
    That sounded too good to be true. And in our case, is isn't true - an OC4J takes up about 50 MB of RAM right after its start. I tried to minimize the Java heap through the OC4J server attbributes in Oracle Enterprise Manager (like "-Xms16") but that didn't make an ounce of a difference.
    So what's the memory footprint of an OC4J inside an iAS instance? And can I reduce it somehow?

    This must be a marketing gag. Client Swing Apps tend to consume more than 3MB.
    I'm not sure but I guess the iAS is the memory eater. We currently have a test installation on a Solaris machine and the iAS pages up to 3GB when accessing the enterprise manager web site. Have a look into the performance guide and try to switch off all unecessary things. Note that there are to different VM switches: -Xms configures the initial heap size a VM should have (growing is expensive) be whereas -Xmx configures the max size the heap can grow (wheares 64MB is default). Again the documenation says that 2MB is then min (not much availabe for OC4J).
    I've you found it - please tell me! :-)

  • Low Memory Footprint JVM needed, Please suggest.

    Hi guys,
    I want a light weight (low memory footprint) Java Virtual Machine compatible with Java 1.5. It should be open source. Can anybody suggest me please. I've googled and tried to use some JVMs like Kaffe and SableVM. But I want some reliable VM.
    Thanks,

  • How to reduce the size of file "BerkeleyDB22.out"

    Follow the file "Building Berkeley DB for VxWorks systems",
    I have finished the building job and get the file "BerkeleyDB22.out".
    The problem is the size of file "BerkeleyDB22.out" is 18MB, it is too big.
    The guide said the size of bdb could reducde to 300k.
    Could you tell me how to recude it ?
    Thank you!

    Hello,
    According to "Notes for VxWorks 5.4/5.5" from the Berkeley DB Reference
    Guide, on "Building Berkeley DB for VxWorks systems" at:
    http://www.oracle.com/technology/documentation/berkeley-db/db/ref/build_vxworks/notes.html
    "A default small footprint build is provided. This default provides
    equivalent to the --enable-smallbuild configuration option described
    in Building a small memory footprint library. In order to build the
    small footprint, you should move db_config.h aside and copy
    db_config_small.h to db_config.h. Then open up the appropriate small
    workspace file via Tornado and build as usual."
    If these directions do not reduce the size, let me know.

  • I want to ask something about firefox. why firefox use very much memory? can you develop to reduce memory comsume? this problem is very distrub in my PC with low memory.

    I want to ask something about firefox.
    why firefox use very much memory?
    can you develop to reduce memory comsume?
    this problem is very distrub in my PC with low memory.
    == This happened ==
    Every time Firefox opened

    How much memory is Firefox using right now?
    # Press '''CTRL+SHIFT+ESC''' to load the Task Manager window
    # Click the Processes tab at the top. (Click once near the top of the window if you don't see tab
    # Find firefox.exe, and see how many kilobytes of memory it's using.
    Showing around 80MB when Firefox first starts is normal. Right now, I have 75 tabs open and it's using 500MB - this varies a lot depending on what you have in the tabs.
    Other than high memory usage, what other problems are you experiencing? (Examples include slowness, high CPU usage, and failure to load certain sites)
    Many of these issues, including high memory usage, can be caused by misbehaving add-ons. To see if this is the case, try the steps at [[Troubleshooting extensions and themes]]. Outdated plugins are another cause of this issue - you can check for this at http://www.mozilla.com/plugincheck

  • Reduce memory consumption when consolidating systems

    We are in the process of consolidating all our DEV and QAS systems to one physical system (HP Super dome).
    We are consolidate more then 20 SAP instances (Java and ABAP) to on physical system.
    The question now is, how to setup the memory requirements (all instance are 64bit and Unicode), during the installation of those instances  we defined 4GB for a ABAP instances and 2 GB for a Java instance (Abap+Java 6GB).
    In our situation we need around 90GB of main memory.
    Does any one have a suggestion how to reduce this amount of memory.
    Because this are all DEV and QAS systems and not all the systems are used at the same time. Is it possible to swapout allocated memory for instances which are not used.
    Kind Regards,
    Evert Schuiteman

    Hi Evert
    Because this are all DEV and QAS systems and not all the systems are used at the same time. Is it possible to swapout allocated memory for instances which are not used.
    This is possible theoretically, but even if no user is connected and no application job is running, there is still activity on a system, so the only way to free ressources is to stop a system when it is not needed. As memory is cheap, you should rather buy more, than running low on it. If the server starts paging, the sap systems will practically freeze.
    You should not forget about the database memory, you will need at least another 2gb for every database.
    In my opinion, you should not consider running 20 instances on one server (hard partition on superdomes). We still have several hard partitions on our superdomes running up to 4 sap instances / databases per partition. I strongly suggest to have a "rolling" consolidation, speaking you add systems one after another. This gives you the possibilty to react if any component becomes a bottleneck.
    Regards
    Michael
