Re: Kernel tuning
On 11.11 you can use the kmtune command:
# kmtune -q param # to check
# kmtune -s param=value # to set
On 11.23 and up you can use kctune:
# kctune param # to check
# kctune param=value # to set
Check the man pages of kmtune and kctune for more detailed info.
Cheers,
Wout

Re: Kernel tuning
#kmtune -s
There should not be space between the kernel tunable and the value.
look at # man kmtune for more details.
