Here are the things I would like (or I should) do for the next releases: * Add a vmstat command (not sure about this, since it already exists in common Linux distributions). * Get rid of the limit on the number of processors (NR_CPUS). * Add more statistics to sar and mpstat (and iostat) when available in Linux kernels. Numerous network activities are already available (see /proc/snmp for example), but I am rather reluctant to display them: There are too many of them and sar becomes bigger and bigger... * Implement a "-P" option for sar to display all statistics on a per-processor basis.
