When I view the system monitor it reports that I'm only using 48% of ram. Same with gkrellm. But all of the command line utilities report different. Here is the output to free and /proc/meminfo. The only reason I can think of is the graphical utilities neglect to count the cache. But isn't that still stored in physical memory. Why is there such a distinction between the two (graphical and cmd-line). Is cache not important?
Thanks in advance
