    By default, buffer cache is 2% of total memory.

    To get the current value of bufhwm, you can:

       sysdef -i | grep bufhwm

    To change it, make an entry in /etc/system such as:

       set bufhwm=10000 <--(value is in k...this example would set it to 10MB)

    Now reboot the system to invoke the new buffer cache value.
