At [Ubuntu Unleashed](http://www.ubuntu-unleashed.com/2008/04/tweak-and-optimize-ubuntu-linux-boot.html) you can find a
|
|
document about different settings to optimize startup times of the system and applications itself.
|
|
|
|
The `noatime` and `nodiratime` settings are unneccessary in Hardy as the default option `relatime` only updates the
|
|
*access time* if the file has been modified after the last access timestamp.
|
|
|
|
You can enable the full power of the [upstart](https://launchpad.net/upstart) manager by enabling multi-threading.
|
|
In `/etc/init.d/rc` at line 24, set `CONCURRENCY=shell`. But beware of slight problems upon booting. Some services might
|
|
be started before depending services are. Also some lines upon startup are printed twice. If you have problems
|
|
getting your machine up and running, change it back to `none`.
|
|
|
|
Another nice feature is adding the `profile` option to the kernel line upon boot. The bootup will take longer than
|
|
usual but the readahead-daemon will catalog all needed files and on the next boot (without that parameter), all needed
|
|
files will be preloaded before boot.
|
|
|
|
On Desktops with much RAM, the [preload](http://sf.net/projects/preload) daemon also speeds up working. |
