I don’t see why you would have to reinstall Ubuntu because of Network Manager. Linux, and even Ubuntu, haven’t always had Network Manager and it’s not a requirement for setting network settings. In Debian all you need is the /etc/resolv.conf, /etc/network/interface(s)? file, and on the off chance the default route gets messed up, know how to use the route add command to add in your default gateway. Of course knowledge about ifconfig doesn’t hurt.

I wouldn’t suggest uninstalling network-manager because I had to reinstall Ubuntu because of it. And I was running off a wired connection.

Haven’t checked any of the other suggestions yet, so I can’t say anything bad about them. *wink*

The bit about prelink is perfectly safe. IMHO prelinking should be done automatically. We have a 64 bit address space. We are not going to use it up. Prelinking does not buy a huge amount. I was a performance engineer for 2 years on an embedded distro. I found it bought you about 4% improvement.

On my system I don’t have to add rootflags=data=writeback or rootflags=data=journal to my menu.lst.

I just did sudo tune2fs -o journal_data_writeback or sudo tune2fs -o journal_data to /dev/sdX.

The entire point of linux is that you can change whatever you want, how you want. And sometimes depending on the quality of distro, or various release of a certain distro, it REQUIRES it to be tweaked. So don’t say “linux doesn’t need to be tweaked”, that’s part of the reason it’s as popular as it is, is because you can tweak it and change it as you see fit.

automounting encrypted drives done with dm-crypt/luks will not work with concurrency.

can the commands
* sudo vim /etc/init.d/rc
* and find the line CONCURRENCY=none and change it to: CONCURRENCY=shell
* Reboot to see the changes. (tired of rebooting yet?)

in any way adversly affect the boot when I have a hd with encrypted lvm?

hey-
just tried a few of these tips

setting concurrency to ’shell’ prevented Ubuntu from automounting my (encrypted) home directory and caused fsck to fail every time i rebooted, luckily i printed out your instructions so i could undo that

using readahead and preload did noticeably improve my system’s speed, thank you :)

didn’t try anything else

To everybody giving the author a hard time, get a life. If you don’t like his methods then just move along. Not everything here is going to appeal to every person in every situation. Just pick and choose what would work for you. And to the person that said they boot their computer only every 90 days, you must never have owned a laptop.
