Did a lot of googling without much success, and now I am here for some
help on Memory Management.
I have total of 8GB RAM, on two servers
Out put from free command,
On Machine 1
total used free shared buffers
cached
Mem: 8104664 8084304 20360 0 7848
64284
-/+ buffers/cache: 8012172 92492
Swap: 2031608 1001964 1029644
On Machine 2
total used free shared buffers
cached
Mem: 8104664 3571624 4533040 0 30568
1016700
-/+ buffers/cache: 2524356 5580308
Swap: 2031608 0 2031608
When I run this command on machine1 and machine2
ps -eo pid,size,vsize,cmd --sort -size | head -n 25 | awk '{print $1
"\t" $2 "\t" $3 "\t" $4}'
I get these results,

1. Why the total on Machine 2 is not same as Memory used,
2. On machine 1, what is using 1 GB from SWAP.
Thank you,
