To get Gentoo Linux to boot faster, you can disable unnessicary services (with rc-update).

But Gentoo also provides some exceptional rc scripts. These scripts allow parrallel loading of services. The result is a system which boots much faster. To enable the parallel startup of services, add or change the following line in the file /etc/conf.d/rc:

RC_PARALLEL_STARTUP="YES"

Now, when you boot your Gentoo distro, it will be ready at a glance!
