You can also sort by any of the other column headers in the File SummaryР В РІР‚в„ўР вЂ™Р’В dialog so you can see which file took the most time, had the most reads, writes,Р В РІР‚в„ўР вЂ™Р’В or any of several other activities. Scroll the data to the left to seeР В РІР‚в„ўР вЂ™Р’В the rightmost Path column (which you can also widen by grabbing its right-mostР В РІР‚в„ўР вЂ™Р’В column header bar and dragging right). This gives you a report of the file I/O activityР В РІР‚в„ўР вЂ™Р’В within the recorded data: File summaryР В Р вЂ Р В РІР‚С™Р вЂ™Р’В¦Р В РІР‚СњР вЂ™Р’В¬lick the Tools menu and then the FileР В РІР‚в„ўР вЂ™Р’В SummaryР В Р вЂ Р В РІР‚С™Р вЂ™Р’В¦ item. If you like, you can scroll through the events to seeР В РІР‚в„ўР вЂ™Р’В whatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s happening, but I have a better solution. In among all of the other events are some relating to disk I/O. Let Procmon run.Р В РІР‚СњР В РІР‚С›s soon as you hear your hard disk thrashing when you think it shouldnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t be,Р В РІР‚в„ўР вЂ™Р’В let it run for a few seconds and then press CTRL+E in Procmon to stop theР В РІР‚в„ўР вЂ™Р’В capture. When you run Procmon, youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll probably be surprised by all the things your system is doing while youР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re not doing anything.Р В РІР‚СњР В РІР‚С›s long as the disk isnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t thrashing (itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s possible that itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s not even beingР В РІР‚в„ўР вЂ™Р’В hit at this point), itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s all quite normal.

Process Monitor, or simply Procmon, is a free tool that you can download here from Microsoft. To find out whatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s happening on your system, weР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll use fairly powerfulР В РІР‚в„ўР вЂ™Р’В system monitoring tool called Procmon. The most common are antivirus tools or theР В РІР‚в„ўР вЂ™Р’В system indexing service, if itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s enabled. It will improve the performance of applications that run mostly in RAM or when loading programs.It could be for many reasons. What it can do is prevent the system from having to use disk-based VM when it runs out of RAM because you are trying to run too many applications concurrently or using applications that are extremely RAM dependent. It doesn't speed up the computer nor make games run faster. If the figure in parentheses is running positive and your hard drive is constantly being used (thrashing) then you need more physical RAM.Р В РІР‚СњР В РІР‚С›dding RAM only makes it possible to run more programs concurrently. If the value in the parentheses is 0 (zero) then OS X is not making instantaneous use of VM which means you have adequate physical RAM for the system with the applications you have loaded. If you open the Terminal and run the top command at the prompt you will find information reported on Pageins () and Pageouts ().

If you are really in need of more RAM that would be indicated by how frequently the system uses VM. The Swap figure represents an estimate of the total amount of swap space required for VM if used, but does not necessarily indicate the actual size of the existing swap file. This will change as applications are opened and closed or change from active to inactive status. The amount of available RAM for applications is the sum of Free RAM and Inactive RAM. Using Activity Monitor to read System Memory & determine how much RAM is used That usually happens when you don't have enough RAM so the system starts using space on the HDD for memory.
