Q: Mavericks and memory (Ram)

Hi

 

Anyone else noticed how Mavericks uses memory ?

I have a new Macbook Air 2013 with 4GB of memory and after a short wile.

The system have used 3.99GB of the total 4GB Isn't that a big problem. Thats can't be right.

I would think that the computer would suffer greatly after a short time of use and the computer

needs to be restarted. If thats true. The new Mavericks ***** big time on Computers with less

memory. Or is there something i don't know.

 

Thanks

A:

As cbs20 said, OS X Mavericks uses RAM much more efficiently than any other previous version of OS X. Mavericks now has a memory compression feature that will compress the memory occupied by applications that aren't being actively used and give the freed up RAM to the application that needs it the most. The result is a much more responsive system and less memory being dumped to a swap file to the HDD which is what reduces the performance of your Mac.

 

If I were you, I would not look at the RAM used number but rather to the Memory Pressure graph that tells you how stressed is the system in terms of memory.

 

I hope this clears out your question.

    I have a 27-inch, Mid 2010 iMac with 3.2GHz Intel Core i3 and 8GB RAM installed. Since installing Mavericks the system has been laggy and unresponsive. I have never had slow responses in the 3 years I've owned this machine. Immediately on installing Mavericks the problems started. I am quite often near the limit of my installed RAM while having only a few applications running. Also, the memory usage on display for the individual processes in the Activity Monitor does not add up to the 'Memory used' at the bottom of the screen. I have read some of the explanations given on how Mavericks more efficiently handles memory usage. If degraded performance is experienced then it isn't working very well, is it? I'm disappointed in Mavericks so far.

    Honestly no! There's allot of working needed with Mavericks. EFI issues are one. The memory is only the base of the known issues. Allot of people started off with memory issues, such as myself then while Trying to use the Recovery System in Mavericks to solve possible permission issues. I've notice that trying to repair my hard drive I've discovered a EFI issue that's unrepeatable. When I restarted Mac, Finder crashed at start and the spinning ball remained for hours; no dock no wallpaper, nothing but the last window I had open and a spinning ball.

    I own a mid 2011 27" iMac i7 3.24ghz,with 8gigs of RAM.

     

    Currently I have only Safari opened (and activity monitor) and I am using 7.99GB with 2.5MB swap used. And my memory pressure is maxed.

     

    Everything is slow and buggy.  And launchpad is feeling this RAM use or leak most.  Launchpad is unbelievabley buggy.  It lags when you enter. it lags when you exit.  Swiping between pages in launchpad is met with pauses and more stutter.

     

    I never had these issues in mountain lion.  If Mavericks is supposed to utilize RAM better, how could I possibly be experiencing this level of lag?  My specs are nothing to sneeze at, and my RAM configuration is more than adequate.  So why the lag?

     

    No one can convince me this is normal, and suggest I upgrade my RAM.  If I was experiencing this lag only after I had a number of apps going, I might concede.  But not simply with just Safari running.

     

    This OS like iOS7 was simply not ready for prime time. My opinion and I am sticking with it.

    Exactly the same here! I have 2009 MacBook Pro with 8GB RAM.

     

    It was really hard for me to fill the whole memory up with apps on Mountain Lion, nearly impossible. But on Mavericks I'm running damned 3 basic apps and the memory is completely full and the computer si SWAPPING ALL THE TIME!!!

     

    Productivity FTW.

    I think this is definitely not a feature. There is clearly some serious problem with memory management in Mavericks.

    I don't care about the gigs used. I care about performance – and swapping to hard drive with mail, safari and itunes running on 8GB RAM is not "utilizing RAM more efficiently".

     

    It is just broken.

    calendaragent hogs memory!

     

    I have an early 2009 24" iMac. After upgrading to Mavericks the Activity Monitor memory pressure went off the charts. Did a clean install, and have been running for a few hours with mostly the apps that come with it.

     

    Still have problems but have noticed a program in Activity Monitor named calendaragent was up in the high 80% of CPU use. I killed the process and it came back with what seems to be normal activity. Everytime an alert goes off it jumps up again and hogs CPU and Memory. Kill it and it returns to normal.

     

    Any one else see this happening?

    I did a "Clean Install" and so far the system runs a lot faster and smother.

    I did a clean install too and my iMac suffers from lag and is buggy.

    WOW, Permissions are Aways needing repair.

    Mavericks might just be Apple's Vista!

    You will need to monitor your RAM usage! I don't know what that other guy is talking about, because if you don't watch out for it, you will experience freezing, spinning color ball or death and final a crash. You will have data curruption. I've installed it 3x things something was conflicting with the install. NOPE!! Mavericks is just F'd up!! This should've gotten released. If you don't believe run STEAM the online gaming app and whatcha what happens to your system performance and processor! Stand by to pull the pull (RESET). Because it's gonna crash your system if it's not the only thing running!

    I have a 27 inch iMac (late 2013) and I was experiencing the same issue for the first day after the update. After 24 hours apple released a firmware update for my iMac and the issues have gone away. I had since added more memory and currently have 3.56Gb used of 16Gb.

     

    So far Marvericks has been stable on all 3 of my systems, 2010 Macbook air with 4GB and 2011 Macbook Pro with 8Gb and 2013 iMac with 16Gb.

     

    Good luck
