Re: extremly low memory usage

I'm just watching gnome-system-monoitor. Which after careful
consideration.....and looking at dstat means I'm on CRACK....GSM isn't
showing cached memory usage....I asume that the cache memory usage is
where data off of the disks would be cached...?

memory output from dstat is this for a few seconds:

---procs--- ------memory-usage----- ---paging-- --disk/sda----disk/sdb- ----swap--- ----total-cpu-usage----
run blk new|_used _buff _cach _free|__in_ _out_|_read write:_read write|_used _free|usr sys idl wai hiq siq
