如何充分利用你的内存

    How much RAM does your PC have? If you run Windows XP, it is probably in the range of 512 MB to 1 GB. Older Windows versions will do the job with less than that, but as soon as you execute demanding applications or more than one application at a time, anything below 512 MB will likely translate into performance bottlenecks.
    The best way to improve Photoshop performance is to make better use of your RAM. Here are several tips to show you how to try this before you buy more. No matter how much memory you have, you could always use more. Installing more RAM is generally the quickest way to better performance. But you can also speed up Photoshop by making better use of the RAM you already have. There have been a lot of times when I’m working in Photoshop and things really start to slow down. When this happens it usually means it’s time to take a look at my RAM and see how much of it is allocated to Photoshop. In this tutorial, we’ll look at how you can speed up your Photoshop performance by using your RAM more effectively.
    What is RAM – Random access memory （usually known by its acronym, RAM） is a type of data storage used in computers. It takes the form of integrated circuits that allow the stored data to be accessed in any order — that is, at random and without the physical movement of the storage medium or a physical reading head. The word “random” refers to the fact that any piece of data can be returned quickly, and in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data.
    As you’re working in Photoshop, click on the right-facing triangle on the status bar near the bottom left of your image window, and choose Show>Efficiency from the pop-up menu. You can use this indicator to determine how Photoshop is doing with the current amount of allocated RAM. If the efficiency indicator goes below 95% then you are accessing the scratch disk which, in turn, will begin to slow Photoshop down. But if your efficiency starts to go below 70%, then you may see Photoshop’s performance increase if you change your RAM allocation or add more RAM.

    你的电脑有多大内存？blablablabla……
    如果你正在为日益供不应求的内存容量发愁，且不想花钱买大容量内存的话，请先尝试我的（好吧……“作者Andy Halls的”）几个小方法来使你的老爷机也可以自如应对ps的工作需要。
    当你使用ps时，你可以在图像下方点击右箭头（如图）选择“显示”〉“效率”，如果所看到的数值低于百分之七十的话，在你增大内存或者优化配置之后会明显感觉到ps运行速度的提升。

    Tip 1: Go to Preferences > Memory & Image Cache and If you’ve never made changes to this, then the Maximum Used by Photoshop setting should read 55% by default in Windows. Increase the amount of RAM in 3-5% increments to start. Click OK to close the preferences. And restart the Photoshop for viewing any performance improvements. Don’t allocate too much RAM to Photoshop because don’t forget that your operating system still needs RAM.
    小技巧1：
    打开属性〉记忆与图像缓存 窗口（cs3的话是在属性〉质量窗口中，其他版本译者so没用过，反正大致的位置吧……），会看到最大值被设定在55%（windows版本的默认值）。增大3到5个百分点，然后点击 ok关掉此窗口。重新打开ps，看看ps的效率是否有所加快，但要切忌，不可以分配过多RAM给ps，因为其他应用程序以及你的系统也要用一部分。
