    defrag the hdd
    I have a Mac Pro, 1 GB RAM, 2x2GHz CPU.

    The problem is that I think the hard drive's contents is very fragmented. Is there a way to defragment it?

    OS X defrags on the fly.

    There is no need to defragment.
    I try to Command+Shift+/ when I can.

    My system has 1GB of RAM, 250 GB hdd (50% used). Do I need more RAM? Usually I am browsing (10 browser windows opened).

    Does anybody know what is the difference between wired, active and inactive memory? Now for instance I have 10 MB of free memory, 180 MB of wired, 545 active and 285 inactive. Does it look like I need more RAM?

    Windows XP also defrags when idle. How can OS X defrag while running apps, or is it also like XP?

    I'd never heard of XP defragging when idle... Whenever I went to defrag myself, it needed doing.

    i think it does something but not well enough seeing as it still needs it manually.

    You're missing the point.

    It doesn't need to defrag.

    Therefore it doesn't defrag at all.

    My saying "it defrags on the fly" was severely layman. It doesn't defrag on the fly so to speak, because it's never "fragged" to begin with.

    My understanding is that it has to do with the way the Mac writes to a journaled filesystem. However, your drive needs to have a fair bit of free space available for this to work properly (I believe the magic number is 25% of your partition has to be kept free).

    Also, while OS/X (and any modern Unix-based operating system) will keep your files as fragment-free as possible, the operating system will not optimize your drive. For that you'll need a tool such as Tech Tool Pro (although iDefrag may also support optimization).

    Windows XP does NOT defrag when idle. It INDEXES when idle. All that means is that your files are optimized for when you have to use the Search. Granted, it does a horrible job at indexing, but it does nonetheless. However, Vista has the option for automatic defragging.

    If you are noticing slowdowns I recommend downloading a program such as Onyx and firstly start by cleaning out all your caches and logs (you will have to reset a couple of times, also be warned that it will be much slower starting up the first time because the cache enables the Mac to boot up in record time).

    Also go into Applications -> Utilities -> Disk Utility and run that to make sure permissions are okay and the disk is okay.

    If you really want to do a defrag then you can do this using Onyx. Apple does not have a built in defrag because it is generally not required.
