My SLES 10.1 zLinux servers have been notorious for not making much

Linux uses extra memory for file cache buffers. When the kernel detects
memory is short, it just allocates less of them and spends more time
accessing the disk.
Linux thinks it is its own virtual memory manager. It does not, one
imagines, co-operate optimally w/r/t VM.
