Memory Cap for a Windows Service to run in the background all the time on Windows 8.1 Device

I have a Windows Store app that would run on a 2GB windows 8.1 Pro tablet. I want to create a service that would run in the background and more than one store app can utilize that service. The question I have is , is there any memory usage limit for the
service to run on a 2 GB RAM tablet?
I am expecting that the service might use 900 MB of RAM when its operational .
Kindly help 

Hi,
For this situation, it seems that you create a wcf service and host the service on windows service which is running on the 2GB windows 8.1 Pro tablet. And other store app in the tablet can utilize that service.
If you want to limit the memory usage for the service, it's recommended that you could host the wcf service on other machine, such as a computer. You just call the service from the store application if you want to invoke the service.
Regards

  • Updating memory capping for zones in default pool.

    Updating memory capping for zones in default pool. Has anyone else run into this where the items for physical/locked/shared memory and swap for zones within the default pool are not changeable? Is this a known bug or feature?
    After moving a zone from the default pool to a user created pool, update these values and then move back to the default pool, I find that I am at that point able to update these values for zones in the default pool now?
    Anyone else hitting this?

    Is it a full zone or a sparse zone?
    prstat doesn't really understand everything that's going on. Its numbers are not accurate when pages are shared (very likely in a sparse zone).

  • So I have an iPad 2 for two years. Has never been dropped or in water or damaged in any way....now the volume is distorted and I get booted off the web all the time. Plus it shows and no service in top left corner. Any one have these issues?

    So I got is iPad as a gift and the same issues I had with my iPhone 4S is also happening with my iPad. Will Apple cover the problem as it lies within there updates or something. All I know I have taken perfect care of both products and volume is distorted. Can't listen to music, I get booted off the web all the time, I can't even chat with Apple icare it won't work and no service shows on top left corner. What is wrong with Apple products? I'm thinking it's time to switch! I've had to change my iPhone twice now......first time for mic not working and then camera shutter kept sticking. Same on my iPad........ I don't want to pay to get this fixed as it's not my fault this is happening...... It's software apparently?

    This really is starting to feel like a hardware issue than a software one.
    Especially if hearing noises when you connecting up your iPad for charging.
    Something happened to your iPad that has nothing to do with a software update.
    This is why I recommend that
    I can't help you any farther.
    It sounds as if you really need to take this iPad in for a repair.
    Since you are reluctant to do this, there is nothing more I can suggest to you.
    Good Luck on whatever you decide to do.

  • Macmini running at 1.83GHz all the time...

    My Mac mini CD 1.83 arrived yesterday. I am surprised that it runs on 1.83GHz all the time even I only open Adium and Safari (but doing nothing). Does it sound alright? cause the temperture stay on 55-63'c all the time, will it be too hot? Any feedback is great....Thanks in advance.

    You raise some interesting points, to which I would like to respond - as much from curiosity as to your conclusions and observations as anything.
    "smcFanControl" is a small app that will allow you to
    set the minimum fan speed to a higher value than the
    default 1500rpm. I have now set mine to 1750rpm and
    the temps are now46/39C (core1 and core2). HD is
    44C.
    I can't entirely understand in what way users of this software feel the standard fan control based in MacOS is deficient - and that if it is in a specific system, why it would not be considered better to have that fault resolved rather than circumvented. That someone has written software to control the fan does not, in itself, suggest users would be wise to avail themselves of it.
    I can not exclude the possibility that this may
    decrease the life expectancy of the fan, but it
    should definitely INCREASE the life of the
    logicboard's components and harddrive.
    'Should definitely' is a good disguise for lack of certainty! There is, for example, no indication that the design of the Mac mini's logic board would benefit in any way in common use from running cooler, and to take one of your later points regarding not wanting to cause vibration by use of the internal optical drive in order to avoid damage to the logic board, no reason to believe that the increased fan speed you have selected will not cause greater vibration impact over time anyway. That said, there is nothing to indicate that the logic board suffers from vibration damage anyway, but if it does as you suppose, then surely fan speed is just as much a potential culprit.
    Someone else has reported that removing the top case
    lowers the temps 12C,so it seems the Mini IS
    suffering from it's diminutive size, not
    unexpectedly..
    It is self-evident that removing the casing would cause the system to run cooler, as would be expected in any conventional design where a box encloses a heat-generating source. The issue isn't whether it runs cooler that way, but whether the heat levels when running in more conventional 'assembled' mode are in any way damaging to the system.
    There is always the possibility that your supposition is right, but if the history of laptops, for example, is anything to go by it would seem likely not. I have both Mac and PC laptops that have been in service for many years combined service and suffered no ill effects of temperature, vibration, even minor impacts and general handling abuse - things which the manufacturers (including Apple) have clearly designed the product to cope with. It is certainly true that both my iBook and TiBook run much hotter than my mini, that their optical drives create far more vibration and their cooling systems are far more challenged by cramped internal design, yet they both function flawlessly, despite continual heavy use. My experience is not, as far as I know, untypical. It leads me to believe that Apple have some competence in their design of products, and that they actually do know what they are doing.
    Ultimately, given that the mini is heavily based on laptop technologies, it seems to me there is no reason to believe it will fare any worse in reliability and capacity to cope with heat and vibration than laptops do - and it certainly has more internal 'space' to allow air circulation.
    However, removing the top case will expose it to
    RFI/EMI, so the chance of it crashing due to nearby
    radio transmissions will be somewhat higher..
    Not really. The sides and base of the mini are metallic, though the clips that hold the sides to the base are plastic and there's no indication of a solid electrical contact which would help screen spurious RFI. The top panel is, however, a form of plastic, which has no RFI screening characteristics, so any stray radio frequency energy in the area is capable of leaking in there. Radio frequencies are not particularly directional (except when approaching microwave levels), and the worst common RFI generators are typically VDUs, which are normally above the mini anyway.
    Much more of a problem than RFI getting INTO a mini is RFI getting OUT! The top panel is transparent to radio because both Bluetooth and Airport antennas are inside the unit under the top and they have to be able to 'see' out, and computers typically generate far more RFI than they are likely to receive in a normal home. Try putting a mini next to an end-fed wire antenna connected to a shortwave (HF) transceiver or receiver. The lack of screen on the wire allows a lot of stray RFI to get into the signal received! People generally don't notice RFI at that level anyway, and of course most modern domestic appliances, such as TVs etc, are designed to screen it out.
    My personal choices are intended to make the mini
    live as long as possible, and this includes not using
    the internal optical drive AT ALL, since any
    vibration from this will be transferred directly down
    to the logicboard. This is not really my idea of
    healthy design..
    I can't disagree with the notion of using an external optical, though in my view not because of vibrational concerns, but simply performance and usability. I think all the indicators are that Apple's designers know far better than I do about what the system itself can cope with and how to design it to be robust enough to withstand time, but the optical drives used are frankly not that wonderful in terms of performance, and can be problematic to extract a stuck disk. An external allows the user to select a unit which specifically meets their need, and is more likely to allow easier retrieval of disks in the event of a failure.
    Seems to me as if Apple's priorities were to make it
    small, good looking and quiet, and they succeeded in
    that. I wonder if life expectancy were ever part of
    this equation..?
    You imply it wasn't, but there is no evidence of that being so, and plenty of evidence it was. One has to accept that no modern product is designed to last an eternity, and the mini is certainly no exception, but as far as it is possible to tell from a model life that is still a little under 2 years, there's no indication that the mini will not last as well as any other system. certainly in my experience, one of mine has been running 24/7 since the end of January 2005, and it shows no indication of getting tired or suffering any problems - and I can tell you without any doubt that in that time it has suffered a far harder working life and higher consistent load than the average home system would get in twice that time or more.
    A number of Apple's designs in the past have shown
    that thermal management is not really their biggest
    strength, so a little self-help here can go a long
    way..
    I can't help but wonder what you mean by this. I own three Macs which specifically are famed for high temperatures; an iBook, a TiBook and a G5 dual processor powermac. The laptops run hot, as laptops do, but are clearly designed to cope, and the G5 has incredibly efficient cooling which means that for the most part the fans barely do more than idle - indeed, the cooling of the G5 is really a masterpiece in its own right. Given that the switch to Intel results in lower overall heat generation than the PPC counterparts, it allows Apple to design systems of far greater power than was possible before without increasing heat generation beyond (or in many cases such as the Mac Pros, even as high) as those systems that went before.
    For example, to get similar performance from a PPC mini that an Intel model is capable of producing, would have required a G5 (or indeed, dual G5s) which would have been impossible to accomplish in this sort of design. The Intel chips now being used allow substantially better performance without markedly increasing heat levels - indeed that was the argument used when justifying the switch. Intel minis do run hotter than the G4 models did, but at substantial gains in performance.
    I'd say that makes for good thermal design - understanding the limitations of the physical space and ensuring the product is engineered with those factors in mind.
    Overall, I think you raise some great issues for discussion, and no small number of common concerns. But, for example, the simple issue of heat levels, often argued as critical to component reliability because of heat stressing, ignores the fact that component and board tolerances and manufacturing standards have improved radically, and that in reality it's not, within operationally tolerable margins the temperature at which the system runs that is the actual problem, but the width of variation of temperatures as the system is in use. Variations around the steady-state operating temperature are what causes the worst effects of heat stressing, most likely to cause component failure, not the steady-state temperature level itself.
    Anyway, I didn't set out with the intention of trying to demolish your arguments, and I hope it doesn't come across as such - indeed, quite the contrary, I wanted to explore the thoughts and issues because they are interesting and of no small value to the community of owners overall.

  • Should I run Firefox with Rosetta all the time?

    I was just wondering if it's a good idea to run Firefox with Rosetta all the time or will the browser run faster if I turn it off when it's not needed?
    I need to turn it on enough to make me think it'll be easier for me if I leave it on all the time.

    It will run faster and use less memory if you let it run natively- whether the loss in speed is made by the convenience of not having to switch it (for whatever reason you're switching) is a personal calculation.

    The figures you mention only make sense on your intranet.  Are you still using the same wireless router.  The verizon one is somewhat limited as far as max wireless-n performace.  For one thing it only has a 2.4 radio.   I like many people who wanted wireless-n performance before they even added a wireless-n gigabit router, have my own handling my wireless-n network.

    The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
    Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

  • How to turn off programs running in the background in the background on iPad

    how to turn off programs running in the background in the background on iPad

    Most apps do not run in the background on an iPad. Their stae is kept in memory so that when you start the app again it will load quickly at the location you last used it. But you can remove these apps from the Recently Used list. Here's how:
    Double click the Home button to show the screen with running and recently used apps. Each app icon will have a sample page above it. Flick up on the page (not the app icon) and the page will fly away and the app icon will disappear. This quits that app.
    Some apps do refresh in the background if you have that Setting turned on. You can control apps there individually or turn off Back Ground App Refresh completely in the Settings App.
