What's your MBP memory usage?

    Here is a screenshot of mine after 2 days with no restart - wired seems absurdly high (600). I don't know if 4 gb of RAM affects it or what, but even after a fresh restart it is around 400, whereas I see others frolicking around at -200... any suggestions? please? should i call applecare? maybe my ram is bad? I have the mbp 2.4 15 inch btw.

    im currently at 450 i restarted about 2 hours ago and havent opened anything since cept safari and adium

    p.s. your kernal_task is eating up about twice what mine is, im not sure what that is though

    that should either make me feel better, or us together feel worse B) are you running 4gb RAM too? would be interesting to note, considering everyone with 200 average wired i've seen is running @ 2.

    Why care aslong as you can run the apps you want to run? Memory are there to be used, an OS which doesn't make use of all your ram is a bad OS ;D

    Your physical memory usage looks about normal depending on what you're doing. I don't see anything that's way out of ordinary.

    Here's something to remember: "Free" memory is space still unallocated to any process, and is freely available for use if a process needs more memory. "Inactive" memory is space that is allocated to a process, but that data has already been cached to disk. If the process that originally allocated the memory needs to access that data, then it will be pulled from RAM instead of the disk. However if a new process needed, say 1.5GB of physical memory, it would still be able to allocate it by pulling from the inactive reserves. In other words, you actually have about 2.9GB of your total 4GB still available for active use by processes.

    For a better explanation that my half-assed one, see http://sg80bab.blogspot.com/2007/03/is-my-mac-using-too-much-memory.html

    i'd prefer to be a little pro-active, thank you very much. ;) plus i've seen plenty of people with around 200 mb of wired, compared to my minimum of 400, i was curious as to why and if it is connected to having more ram. in fact, other than squeeks i haven't heard of ANYONE hitting 400 (not running vmware or parallels, etc.).... I mean, i'm not even running a virtualization software... if I was, I can't imagine what my wired would be...

    i know, the strange thing is, all the processes don't seem out of the ordinary relative to others... yet my wired seems way out of the ordinary. What is using up all that memory and why? If 200 mb is normal, I would prefer to be using 200 rather than 400, especially considering i run into tasks where all my RAM is being used...

    You have 2.16GB of inactive memory and another ~700MB free. I'd be surprised if you get near running out of allocatable memory anytime soon. What exactly do you think is going to be so memory intensive that its going to eat up nearly 2.9GB of memory?

    Plus, from the look of all the junk you've got running on that machine I wouldn't be surprised that you had a rogue kernel extension from some third-party app that wasn't quite ready for primetime gobbling up memory with a nasty memory leak...especially since you said that's memory usage after running for two days. I'm not gonna make any sure predictions without seeing the machine and seeing what's running, but its certainly possible. Is your memory usage much lower right after rebooting?

    working with 500 mb and way up ps files, while also running ai to move back and forth certain elements. final cut and ae seem to do use quite a bit as well.

    after a fresh restart my memory usage borders 400.

    thank you for the response though, i will look into the possibility of a rogue kernel extension more. I am still curious though as to whether this has to do with systems with more ram in general? the only process i have running after a restart that perhaps other 200 mb users don't have (or i haven't seen) is bookbot widget and peerguardian.... it could be peerguardian? I also have little snitch running, i dunno.

    I have no idea what is considered normal, but based on my MBP I doubt it is 200. I just did a clean boot -- nothing running except Finder and some widgets -- and got this:

    this is very interesting considering you are the first person who has posted a picture using 4 GB of ram like me (not sure about squeeks... the other report of 400) and getting around 400 after a fresh restart (with no parallels/vmware). So perhaps OSX detects the doubling of RAM and in turn doubles the amount of memory used on critcal processes to compensate/speed it up? I don't know, it seems strangely logical, but at the same time not. any knowledge on this matter or other 4GB users postings would be greatly appreciated.
