I don't know about you guys but the RAM issue is becoming worse and worse. In the Users/my-username/Library/LaunchAgents there are even less items. In the Startupitems folder there are few things.ģ.2. three instances of apple- / Kind: Unknownģ.1.On the start-up disk the Library/LaunchDaemons as well as the Library/LaunchAgents folders there are different stuff belonging to Adobe, Apple and some others.In the Preferences - Login Items I have 4 items: I don't have a System or I couldn't locate it. Yet there is a number of stuff that don't fit.ġ. The claim is that modern CPUs are so fast, and HDDs/SSDs so slow, that it pays to page to compressed RAM rather than always going to a drive. The computer compresses the contents of an area of RAM into a smaller area of RAM when there is a need for the data, it reverses the process.
Recent versions of Mac OS X have featured the ability to page to compressed RAM. Usually this is space on a HDD or SSD – and is extremely slow to access compared to RAM. The point of virtual memory is to make it look as if your system has more memory than it really does, using slower, larger, backup storage. I am very cautious now.Ĭompressed Memory probably refers to how much memory is being used for a form of virtual memory. I have already been burned several times after tossing stuff that seemed useless and that were actually indispensable. I should have mentionned I am running El Capitan.Īs a matter of fact I don't understand in the Activity Monitor what the columns Real Memory, Compressed Memory, Memory and Purgeable Memory exactly refer to. Hi folks, I am back after a busy Saturday. I don't think it will be easy to come up with an example of a production critical task being denied because of the types of processes you're interested in disabling. it's a lot like a lifetime manual transmission driver not understanding that modern automatics/CVTs are actually faster and more fuel-efficient than a stick.
Modern OS memory management is definitely not a case of "add up the numbers and that's the total." Between RAM compression, VM, dynamic management, etc. And there are so many of them, where do we stop.Dropbox? Password manager? Auto backup? If you disable them, the next time the software updates, the update installer will often notice the disabled components and "fix" the installation by re-enabling everything so you have to start over. There are so many of those mini processes that even if you do manually override them, it would be a lot of work to keep up with them as they change or get updated or added with new software and OS updates, sometimes automatically. Just because this or that minor process says it uses 400MB or 500MB will not prevent a more critical process from requesting what it needs from the OS. The amount of RAM stated may not be the amount actually used, because a large portion of it may be compressed or swapped out unless actively in use. I have decided not to micromanage all those things.
