Whatever you do, DON’T quit or force quit programs listed in the Process Name column. Break your projects into smaller files, so that they require less RAM to run.
Add more RAM, if your computer supports RAM upgrades.If you find your system constantly requiring swap space, you have a limited number of options: In an ideal world you want this number to always be 0. The amount of hard disk storage used for swap files, because RAM memory is too limited. The amount of memory used for cacheing files stored on your hard disk to minimize excess reading or writing to the hard disk. Wired Memory is, essentially, RAM used by the operating system. App Memory is RAM used by active applications. The amount of RAM currently used by all active programs. The amount of RAM installed in your system. Just sit there and admire how much is going on in your computer that you were not aware of.Īt the bottom of this window is the section we want to watch: While fascinating, I STRONGLY!!!! recommend you not mess with this list. The list below shows all the active (running) processes (programs) and how much RAM they are using. When the program starts, the five tabs at the top allow you to monitor activity in five key functions of your computer: CPU, Memory, Energy, Disk and Network.Ĭlick the Memory tab. You measure swap activity using Activity Monitor, which is located in Applications > Utilities > Activity Monitor.

If you have limited free space on your hard disk AND you are swapping, program speeds grind almost to a halt because the OS is spending all its time moving data between RAM and the very slow, very limited free space on a hard disk. The more swapping the OS needs to do, the slower programs will run because moving data to and from a hard disk is far, FAR slower than moving data around in RAM memory. (My current recommendation for minimum RAM for media editing programs is 16 GB.) The more RAM you have installed, the less swapping is necessary. On its own, the OS is very efficient and, given the amount of RAM in currently shipping computers, you shouldn’t see any swap activity when only the OS is running. Swap behavior only occurs when programs are running. I also have two external hard drives attached which hold all my media and related files.Įarlier, I mentioned that when RAM is limited, the operating system will swap program segments and data temporarily to a hard disk. On the iMac I use to write these articles, I’m using a 3TB Apple Fusion drive which is a combination of SSD and spinning media hard drive as my boot drive.
And, if you have access to an SSD drive, using that for the boot drive (the one that holds the operating system) will further improve performance. The more free space you have on your boot disk, the faster most applications will run. NOTE: Just for reference, the operating system takes about 30 GB to store. (In my example above, I’m using about 11% of total capacity, leaving about 89% free space.) Your goal should be for Available to always exceed at least 20% of the Capacity. This is the total amount of storage currently being used to hold files. This is the total free space (unused space) on the selected device. This is the total storage available on the selected device. In the General category at the top of the Get Info window, your computer displays three values: Select the hard drive / RAID / camera card / storage device you want to check.Ĭhoose File > Get Info (shortcut: Cmd+I) and the Info window opens. There are multiple ways to determine free space on any storage device, but, for me, this is the fastest and easiest. When you quit a program, all data swapped to the hard drive is deleted. Swapping moves portions of programs and files that are not immediately needed to a hard disk temporarily. Swapping data, on the other hand, is done automatically by the operating system and only when a program is running and needs more RAM than is available. When data is purposefully saved to the hard disk by the user, the entire file is saved and remains on the hard drive even after the program quits. NOTE: Swapping data from RAM to hard disk is not the same as saving it. Worse, if there is limited free space on your hard disk, swapping files will dramatically slow down a program. Swapping data from RAM to hard drive always slows the performance of software. In addition, if you have limited RAM on your computer, the operating system will “swap,” or transfer, portions of data from RAM memory to your hard disk to make room for data which you are actively working on. Monitoring the free space on your hard disks is an essential activity when you are working with media whether you are editing audio, video or photographs.Įvery editing program creates a variety of work files during the editing process.
