 | | To support a wide variety of applications, ranging from a single-user workstation system to a multi-user timesharing system, the UNIX operating system has always offered the system administrator a number of parameters that can be “tuned” to make the system perform better under specific types of load. Some of these parameters control the behavior of the operating system kernel proper: how many file table entries to allocate, how much memory to allocate for interprocess communication, how many process table slots to use, and so forth. Other parameters control individual processes, such as how many open files a process may have, how much memory it may use, and how large a file it may create, to prevent a single process from consuming the entire system's resources. | |
