After perfect installation to Fedora 12, here is what I get from Show memory usage page: MemTotal: 1564954624 (1,564,954,624 - 1.5 GB) MemFree: 487636992 (487,636,992 - 487 MB) How is this possible? I think it's too much... Don't you?
Thats normal on Linux. The Linux kernel uses unused ram to cache data from the harddisk for faster access, it does not mean that the memory is used by currently running applications. The kernel frees this memory automatically if new starting processes require it.
