How To Speed Up Linux Booting Posted Sunday, March 25, 2007 @ 8:33 PM by mayhem
"A common complaint about Linux is the amount of time the operating system takes to start. Like Linux itself, there are plenty of options and lots of flexibility for boot-time optimization. From dependency-based solutions like initng to event-based solutions like upstart, there's an optimization solution that should fit your needs. Using the bootchart package, you can dig in further to understand where your system is spending its boot time to optimize even more." (Source: Slashdot)
