I have 8Gb memory installed. When I quit all of my programs i have free 500Mb. After purge command this value increased to 700Mb. Where is my 8Gb? It is marked as WIRED...
Reboot helps but only for 1 hour...

Activity Monitor has columns that are not displayed unless you ask for them. Try "View -> Columns -> Real Memory". If you show All Processes, you may be able to find the process(es) that are tying up memory. You can click on a column to sort the results. My current machine has process 0, kernel_task, at 1.55 GB. Firefox has 1.04 GB. Surprised me. Private Memory could also be a culprit.
purge- is default terminal program. – k06a May 23 '13 at 12:54
