Topic: Memory, and useage of

[Dan Williams]

Hi,
On a failry stock install of SME5.6U4 with 1GB Ram I am surprised to see when issuing the "top" command that it states:

118 processes: 115 sleeping, 3 running, 0 zombie, 0 stopped
CPU states:  0.0% user,  0.1% system,  0.0% nice, 99.8% idle
Mem:  1029744K av, 1010988K used,   18756K free,       0K shrd,   71936K buff
Swap: 265064K av,  0K used,  265064K free,  785552K cached
Wha does this look like to you? The way I see it, is there is not much memory left? I have rebooted and that seems to change the "FREE" amount considerably, but it ends up looking like this in no time at all again.
Can anyone offer their opinion or explanation please.
As well I would be interested in a link in reading up further on how to interpret this if anyone has bookmarked on they liked.

Linux handles memory differently and caches as much as it can, hence the large cached figure. As soon as something new requires that RAM it will be freed. If something that has been run is run again then you benefit from the caching.

I don't think you have anything to worry about.
