My Laptop runs slow and often spins when I open the browser or other apps sometimes and found the load average to be less than and also about 300MB free memory,till I notice swap as 40MB/256MB on iStat. Questions: 1. How do I find out what process is causing the swap? The top does not show swap, and the vm_stat does not show swap either like vmstat does. 2. In the memory what does the wired, Active, Inactive memory mean?The only value that makes sense is Free.
