Those 2 (/etc/sysctl.conf and grub) are unrelated.
With sysctl you can configure kernel parameters. You can either do this dynamically ("from the prompt") or at boot (using /etc/sysctl.conf as input).
Have a look at these links:
- sysctl (wiki)
- sysctl.conf example and links
A word of advise: If you are going to experiment with sysctl, do make sure you know what you are doing. Do an extensive search on the net and/or ask the LQ community to help if you are unsure.
Although you can tune many, many kernel parameters you do have to know what you are doing. Setting the wrong values can have a big negative impact on your system.
