Hello,

I need more explanation of "free -m" linux command.

[root@xxxxxx /]# free -t -m
             total       used       free     shared    buffers     cached
Mem:          2026       1817        208          0        404       1035
-/+ buffers/cache:        377       1648
Swap:         2047         17       2030
Total:        4074       1835       2238

Open in new window


As shown, we have 2G total, 1.8G used and 208 Megs free. Everybody will say that we need RAM, but
inline total : 4G total, 1.8G used, 2.2G free, so do I really need more memory ?

Is it good to use swap memory ?

We ask this question because the server is suddenly slow.

see this image ( Plesk shows 40% of memory used ) ?
 comparaison between 'free -m' and Plesk.
thanks,
