Appendix A: IRIX Kernel Tunable Parameters
This appendix describes the tunable parameters that define kernel structures. These structures keep track of processes, files, and system activity. Many of the parameter values are specified in the files found in /var/sysgen/mtune and /var/sysgen/master.d.
If the system does not respond favorably to your tuning changes, you may want to return to your original configuration or continue making changes to related parameters. An unfavorable response to your tuning changes can be as minor as the system not gaining the hoped-for speed or capacity, or as major as the system becoming unable to boot or run. This generally occurs when parameters are changed to a great degree. Simply maximizing a particular parameter without regard for related parameters can upset the balance of the system to the point of inoperability. For complete information on the proper procedure for tuning your operating system, read Chapter 11, "System Performance Tuning."
