How much does in-memory replication boost txn rates?

I posted the note below on the weblogic.developer.interest.clustering" list.
          As a supplement to that question, I'm wondering how much of a boost to
          transaction rates that anyone sees from using in-memory replication with
          WebLogic?
          =====================
          How many peak/average transactions per second is anyone pushing through
          WebLogic? With what response time? On what version of WebLogic? With what
          sort of a configuration?
          If you don't have transactions per second, any other measures of performance
          and scalability would be interesting.

          Mike -
          Thanks for the reply -- I phrased my question poorly. What I intended was
          this:
          - Compared to saving context to disk (so that it is accessible across
          servers in a cluster), how much does in-memory replication boost transaction
          throughput rates?
          I'm just wondering if anyone has measured the difference in their
          environment.

  • HT1651 How much does more memory  cost?

    I need more memory asap on my late macbook 2009.  How much does that cost?!
    Also, it keeps telling me that I need to free up start up disk space...how do I do that?  I've been deleting all sorts of unneeded programs, apps, files, etc? 

    I agree with Kappy that your issue is with hard drive space, not RAM (memory), but if you should decide you need more RAM as well you can purchase it at a reasonable price from Other World Computing or Crucial.
    For the issue of your startup disk being full the first thing to try is to empty your Trash. Lots of people put items in the Trash but fail to empty it, a necessary step for reclaiming that hard drive space.
    If emptying the Trash still does not leave you with sufficient disk space, you can either get a new larger internal hard drive and move all of the contents of the current drive to it, or you can purchase a compatible external hard drive and move some of the contents of your internal drive to it.
    Good candidates for things that can be moved would be your iPhoto library and your iTunes library, since both audio files and picture and video files tend to take up a lot of space. If you want instructions on how to do either of those, post back and we'll keep helping you.
    Best of luck.

  • HT1270 how much does a memory upgrade cost

    i wold like to upgrade the ram on my macbook pro but i dont know how much the chips cost

    That depend upon which MBP you have and what RAM you wish to install.  I suggest that you look at the OWC and Crucial websites for what is available for your MBP.  Prices will be listed there.

    Do you have the old for new service? Can I upgrade my iPhone 5s to the new iPhone 6 and how much does it cost?

    Actually, in the US at least the website states
    You can recycle your iPhone at the Apple Retail Store and get immediate credit for its value toward the purchase of a new one.**

  • It seems like I just missed the interval for the hard disk replacement program. I purchased in March 2009 a 24 inch Intel iMac . How much does it cost to have apple support at an Apple Store replace a hard drive?

    My hard drive continually has the floating beach ball and will take massive time to fulfill a request. And then will not boot up...so then I have to do a restore and rebuild hard drive from a past saved time machine version. Works for a little bit...then the floating beachball comes more and more...until it will not boot up again. So then I restore from a previous time machine saved version....and again it works for a day or so ... until it happens again. Now it's happening faster and faster...so I think my hard drive is dying.

  • How much does boot camp take speed from a macbook bro 15

    Iam a architecture student and i need to buy a macbook for designing, And some of the program's doesnt work on OS-X such as Revit unfortunately , And i need to know if it does effect to much on the speed, please if anybody knows help me!!!. If its possible how much does it take, 50% 30% of the general speed.

    When using Boot Camp, only one OS is running at a time. That OS has sole access to the computer's hardware; it won't affect Mac OS X's performance when running it.

  • How much does Premiere Pro and After Effects rely on the hard drive it's installed on?

    This may be a really dumb question, but how much does Premiere Pro and After Effects rely on the hard drive it's installed on if all your video files, assets, disk cache, etc are on different drives than the one the program itself is installed on?
    The reason I am asking is that I currently have a "relatively" slow Sata II SSD for my C drive that has just my OS (windows 7 64bit) and programs (adobe editing programs, no games) installed on it and nothing else. All of the files used in my projects are saved on either a very fast Sata III SSD or a slower HDD depending on what the files are. For example, disk cache on the Sata III, stills on the HDD.
    Being cyber monday I have the opportunity to buy another very fast Sata III SSD to replace my current Sata II SSD C Drive (just OS and programs). Both synthetic and real world benchmarks show a near double in performance. I just want to know if anyone thinks the upgrade is even worth it because for all I know there won't be any increase in performance since no videos, still, cach, etc will be stored on the C Drive.
    The alternative is to get a second monitor because I currently only use one 21" monitor.
    I suppose another alternative would be to not buy anything on the cyber monday deals and just save money for something else.
    Any advice or input would be greatly appreciated. Thanks!

    Thanks Alex! I think you are right about not being able to notice the difference between the SSDs. I ended up finding a deal to get about $80 off a great monitor that I've been looking at for a while and decided to pull the trigger on it. I thought about it and realized that there have already been a bunch of times where I want to watch a tutorial on youtube and follow allong in AE or PrePro, but have to keep switching windows. I also frequently want to have my video preview on a separate monitor so I can have a taller timeline window. This monitor will help a lot with that. Thanks again for your help!

  • Iphone 6 plus screen crack, how much does it cost.?

    Had iPhone 3,4 and 5 and never had protective case. over the years phones fell several times. they even fell down on road, except for small dings on the edges they  never had cracked screens.
    6 plus screen cracked after falling less than 3 feet (from back pocket) on to wood floor, even with protective case (bought case so that it won't slip from the hand, phone being so slippery).
    I think,  Quality of apple hardware and software went down drastically with latest round of refresh.
    iOS 8 has lot of issues.
    usually hardware is high quality but seems like that is not the case anymore.
    Even worse part of the experience is:
        had online chat with apple support person and (Julian) he/she mentioned he/she will give me a deal for $129, fixing the screen.
        After a quick google search, seems like list price of fixing the screen is in fact $129, I don't think there is any deal  (see the question).
    Question::
      How much does it really cost to fix the screen crack. screen is working fine.
    https://www.apple.com/support/iphone/repair/screen-damage/      
    Page lists price as $129 but support live-chat person mentioned around 350 something and offered deal of $129. 
    Did anyone had the iPhone 6 plus fixed ? if so how much did it cost, without applecare.??

    Whole unit replacement of an iPhone 6 Plus is $329 USD + tax.
    Screen replacement only is $129 USD + tax.
    Either you misunderstood, or they were simply trying to explain how a screen replacement is less expensive than whole unit replacement.
    Why do you care if it's a 'deal' or just the normal price?  Are you wanting to be treated special and different from other Apple customers?

  • HT1338 how much does it cost to get the latest version of safari

    how much does it cost to get latest version of safari

    What MichelPM suggested is the SAFEST solution. Firefox is a better browser than Safari, and you will not be faced with any potentially crippling consequences of a full OS update.
    You will presumably have to update your system at some point, and you should prepare for that by maintaining a full, up-to-date backup of your current main system on an external hard drive. You can use SuperDuper ($25) or Carbon Copy Cloner (the legacy version, 3.5.7) to clone your current system to an external drive. This drive will be bootable and will provide you will a safety net if you decide to install Yosemite at some point.

  • My mac pro screen has vertical lines... How much does it cost to get it fixed?

    My mac pro screen has vertical lines... How much does it cost to get it fixed?

    When you fail to give information on the exact model MBP that you have, how do you expect anyone to provide you with any specific information?
    I suggest that you go to the iFixit.com and Powerbookmedic.com and look for parts and prices.  That naturally assumes that you know what parts are defective and need to be replaced.

  • How much does it cost to unlock iphone 4s

    Hey guys im planning to buy a iphone 4s locked version as the unlocked version is costly how much does it take to unlock it

    I think it is free but not all carriers will do it and you have to make sure you are clear of any contract obligations to them.

    how much does apple charge to factory unlock my i phone

    $0.  they dont unlock phones... Carriers do.
    ATT will unlock your phone after ur contract is over.
    Verizon/Sprint will unlock GSM portion but they have conditions that need to be met. 
    Best thing to do is call the iPhone's carrier...
