When using the top command I get the following in regards to memory usage. Mem: 223M Active, 970M Inact, 175M Wired, 50M Cache, 112M Buf, 73M Free Swap: 3029M Total, 12K Used, 3029M Free Can someone advise me which figure relates to actual physical memory which is available. I can't work out if it is the 970M Inact or the 73M Free (i.e. the last figure). Any advise greatfully received. Thanks Regards Phil.
