The size of the paging file varies depending on exactly what programs are running, what those programs are doing, the size of the documents you have open, the multimedia content on the webpages you are viewing, etc. In addition, virtual memory is used regardless of how much physical RAM is available. The OS manages this, determining what data can be stored on the hard drive to save system RAM even when there's plenty to go around. Thus, the paging file increasing size from 180MB to 210MB isn't actually abnormal.
In short, no worries.
the pf usage on my computer was about 180 when turned on. i found out i only had 512ram/750 virtual memory.
so i got 2gb ram and installed,,,changing the vm to 3gb min/3gb max.
now when i turn on the computer, pf usage show as 210!!! is this right? shouldn't it be lower.
i have my machine running trim. nothing in the background except essentials.
