Check the linux Startup time-Linux Enterprise Application-Linux server application information. The following is a detailed description. You need to know how long it takes for your server to start up and what processes and services you have started. In addition to viewing logs, you also have a more graphical method, that is, using the help of the bootchart software.
You can go to http://www.bootchart.org to download
1. for debian machines, apt-get install bootchart is more convenient.
Then in vi/boot/grub/menu. lst
Root (hd0, 0) kernel/vmlinuz ro root =/dev/hda1 init =/sbin/bootchartd initrd/initrd. add init =/sbin/bootdchartd to the end of img (Note d)
The second case is like using slackware 12. After checking a lot of information, you can get it done.

# Tar xvfj bootchart/bootchart-0.9.tar.bz2
# Cd bootchart-0.9
#./Install
Complete
Test:/sbin/bootchartd
Usage:/sbin/bootchartd {init | start | stop}
Successful
Slackware12 is guided by lilo. So I can't use the grub method above to add init =/sbin/bootchartd to lilo. conf.

Boot:
Prompt
Write your linux name as follows:
