4.3.3. Performance
To a user, performance means quick execution of commands. To a system manager, on the other hand, it means much more: the system admin has to optimize system performance for the whole system, including users, all programs and daemons. System performance can depend on a thousand tiny things which are not accounted for with the time command:
• the program executing is badly written or doesn't use the computer appropriately
• access to disks, controllers, display, all kinds of interfaces, etc.
• reachability of remote systems (network performance)
