Mac os x 10.8 inactive memory


What do the users think about Memory Cleaner

Show top 5 memory consuming processes: When setting a check mark here, System Monitor additionally collects information which currently running processes are responsible for the major part of memory usage. The process names will be listed in one section of the menu, sorted by their contributions to the total memory consumption. The corresponding percentages will be listed as well. It is optionally possible to replace the display of percentage values by readings for absolute consumption of real memory.

You can select between one of the items with percentage values and with resident memory sizes real memory. Retrieving the process list is a costly operation for technical reasons.

The load caused by System Monitor itself will slightly increase when you enable this feature. The affected memory is part of each of the processes memory areas, so it will be counted multiple times although it was allocated only once. Show history graph: After enabling this item, the history of memory usage within the last 30 seconds will be added to the menu.

Using history graphs to visualize memory usage typically does not make much sense. After the system has reached its typical workload after start, the usage of memory should stop varying greatly, if possible. Show paging operations as number of swapped bytes: In case this option is selected, the readings for page-ins and page-outs will not be shown as counters in the menu, but as total amounts of transferred memory sizes.

If you like to monitor main memory of the system, perform the following steps: Ensure the control window of System Monitor is open. Make sure the check mark Monitor this item is set at the right side of the window. Use the pop-up button Terminology to select one of the presentation styles that should be used to compute and to name the different usage types of memory.

Improving memory efficiency

The different display styles will be explained in the following sections: Classic designations OS versions up to Active: normal used memory. Inactive: free memory which has not been cleaned by the system yet. Delaying clean-up of memory to the latest possible moment is a technique to improve efficiency. The buffers used by the operating system kernel to speed up disk and network operations are also part of the inactive memory.

Free: normal free memory. Physical: RAM installed in this computer. Mavericks designations OS X In OS X Mavericks and the first three versions of OS X Yosemite, Apple switched to the following terms for referring to memory use: Apps: memory used by applications and the operating system. File Cache: memory used to speed up access to files on disk or on network file servers. Wired: memory marked not to be available for swapping. This is equivalent to reserved memory in classic display style.

Understanding Compressed Memory on the Mac

Compressed: memory used to hold contents of pages which are basically swapped out, but are not stored on disk, but also in RAM in compressed fashion. Modern designations OS X The following designations are used: Apps: memory used by applications and the operating system. The following elements can be used: The label MEM memory in small, vertical print to designate memory values and to separate them from other icons in the menu bar. The label MEM in large, horizontal print. The display of used U and free F memory as plain text in two lines using small print. The display of used memory as text in percent.

The display of used memory as bar chart. The display of used memory as pie chart. The display of memory usage history for the last 30 seconds. Note that on the old Solaris systems, you needed at least as much swap as real memory or you could not use the real memory. That was a real bummer but long since fixed in modern linux look alikes such as MacOS. Running a large windows VM, re-computing some Bridge CS3 thumbnail, and other intensive task was as fast as usual. Also Office took some jumps. But with this tweak they cant finish the first And yes, like some mentioned before.

Memory management of OS X a least And also yes, inactive memory!

How to Purge Free UP Inactive RAM Memory - MacOs (Mac OS X)

That's my experience, which hopefully HTH someone. I'm a bit skeptical about the measurement of memory when pager is disabled. I fact I don't understand the result: why is active memory stays low when I'm running big software?

The spikes of memory consumption are due to Left 4 Dead 2 around Fri , Fri Active memory stays about the same value. Second one shows memory usage for a week: from 3rd to 8th of June, pager is active, after, pager is deactivated. Before deactivation, you can see the effect of playing Left 4 Dead 2 every memory spikes. It clearly shows that playing L4D2 increases active memory usage by approximatively 2 GB when pager is active, and by nothing when pager is inactive. Note that on the 8th of June, uptime of the system was around 50 days, so active memory being so high is ok. I am trying this, but sudo keeps asking me for a password, which I cannot figure out.

I assume this is because of the extra privileges on sudo. Do you know how to get that sudo password easily, or how did you bypass it?

Memory Leak on 10.8.1

AFAIK the password should be the pw for the user you are currently logged in as I think you have to be using an admin account. Thanks for the fast response! I tried that several times, and was only able to pull it off today. I may have typed my pw too quickly or something Now I get the error: launchctl: Error unloading: com. Thanks for the help guys! I had inadvertantly run the unload command twice and I think I got that error the second time since it wasn't loaded anymore.

Maybe the command previously ran successfully and you didn't notice?

If you run the same command replacing "unload" with "load" then it will either load it or say "already loaded," so you could try loading it and then unloading it again. I'm gonna have to try this on my new iMac. I'm sure it's not going to run out. Awesome tip. I'll see how this works. Just applied that tweak - and for the last three hours haven't seen spinning beach ball even once! Still got 2GB free mem and everything works like a breeze. Mac Pros or those with rpm might not see that much difference. Right now it feels more like working o a Mac with SSD drive.

I've got 8GB of memory but I have put Activity Monitor in a dock to show my memory usage - and it is not that bad. After three hours of web surfing, film watching and photoshopping photoshop has separate VM still around GB free. But seriously I have almost forgot how the spinning beach ball looks like : Will keep posting in case of unusual behaviour. OK Update. Max mem usage was around 6GB. No kernel panics, no complaints, just system freeze. Beside that one hiccup everything was just peachy - even opening three mb files in TextWrangler was absolutely fine.

Running Macbook pro i7 2. OSX With this hint, launching apps and running iphoto noticeably faster. Previously Word was taking too long too load, so much so I turned off Word Document Gallery at startup. Now the Gallery comes up more than quick enough, so I can leave it on. No longer missing SSD as much. Haven't had any probs running almost every app I have concurrently. On activity monitor, seems to free RAM faster rather than holding it inactive.

Too Much Inactive RAM, Too Little Free RAM - Apple Community

I wouldn't say that it's disabled VM entirely, since I still have a GB VM on activity monitor, but whatever it's done, it's working great on my system. Thanks for the turbocharging tip!! I think this trick could work if you are lucky enough. I did it: yesterday I disabled the virtual memory and checked the memory usage in real time with menumeters during an afternoon of work with xcode in iOS programming.

The wired memory kept to fill up the total memory available 8GB , and I didn't notice any speed bump, but I have an SSD, so I'm not sure, because memory swapping with an SSD could be fast enough to make the system sufficiently snappy on its own. After some hours 3 or 4 the memory was completely full, and the system didn't crash: it simply stopped to work, I couldn't do anything, no kernel panic but the macbook pro was freezed. Actually I was expecting that but I love to make experiments , so I shut off the macbook pro pressing the button for two seconds, and then I rebooted.

Nothing happened right after that, but this morning OSX did some silly things, like resetting the system date to , and asking for network permissions for all the system level services. Also, mail asked me again for all the account and passwords.
