tuning

There are several tools available for determining the current size of the various

kernel parameters on the system. Some of these tools can also describe how the

sizes of these parameters are calculated in the kernel. Additionally, sam(1M),

kmtune(1M), and adb(1) can be used to change the values of the kernel

parameters.

The /stand/system file is the configuration file used to build the kernel. Among

other things, it contains a list of the modified kernel parameters used on the system.

Since it is an ASCII text file, it can be viewed with any text editor. Changes made

to this file only take effect when a new kernel is built referencing the changed file

via the mk_kernel(1M) command.
