Questions about the desktop backgroung

[Applexilef]

Hey ladies and ladies

I like to have my background picture change every once in a while, so I was wondering, does this feature eat up your RAM? I just want to know if I'm reducing the performance of my computer by having this feature on.

Peace

I haven't noticed a drain on system resources, and I've got mine set to change every five minutes.

I have it set to change every 5 seconds, and haven't noticed any loss in performance. I don't have any statistics to back that up though.

you have my vote..i even noted down ram usage before and after ..hardly any...

i guess just further confirmation here... i am running an older ibook with deskop changing and don't notice any slowdown.

the only desktop that has slowed anything down was when i was using the "flurry" screen saver for the desktop, but no surprise there.

Does this help?


TITLE
Mac OS X: How to View Memory Usage and Installed RAM

TOPIC



Use the About This Mac window and Process Viewer to check the amount of installed RAM (physical memory) and the amount of memory being used.


DISCUSSION



Viewing the amount of RAM (Physical Memory) installed

1. Choose About This Mac from the Apple Menu.
2. The Memory field specifies the amount of RAM installed in the computer.

Note: Mac OS X does not display the memory allocation and usage levels of individual applications in the About This Mac Window. Mac OS X automatically manages memory allocation and usage. This is different from earlier versions of Mac OS.

Viewing memory usage

1. Open ProcessViewer (located at /Applications/Utilities/).
2. Mac OS X processes and applications are listed in the Process Viewer window. The column on the right, "% Memory," indicates the percentage of RAM in use by an application or process at the time of sampling. See Note 1, below.

Advanced users may use the Terminal to view memory usage. Please see document 106415: "Mac OS X 10.0: How to View Memory Usage With top"

Notes
1. If 2.0 GB RAM is installed, usage is not correctly reported. See technical document 107338, "Mac OS X: Process Viewer Displays Incorrect "% Memory" Values if 2.0 GB of RAM Is Installed".
2. It is normal for some processes to use very little RAM at times, such as 0.0% or 0.1%.
3. It is normal for a process' memory usage to change dramatically from one sample period to another, depending on how you are using your computer.
4. Not all application names in the Process Listing window are easily recognized. For example, Microsoft Internet
Explorer 5.1 may appear as "LaunchCFMApp." This is normal.
5. Classic applications do not appear individually in the Process Listing window. The Classic environment appears as a single process (TruBlueEnvironme). This is normal. See Note 6.
6. ProcessViewer itself is listed because it is an open application. This is normal.
7. In Mac OS X 10.2 or later, The Memory/Versions section of the Classic preference pane displays information about the Classic environment similar to what is displayed by Mac OS 9 when you select About this Macintosh from the Apple menu. A scrolling list of active Classic applications and their memory usage is displayed, and a checkbox controls whether background-only applications will appear in this list. It also displays information about the installed versions of the Classic environment.
