Here I try to explain how to get prelink running in Ubuntu for your reading pleasure
Here is a screenshot showing, Fedora 13 has prelink installed and enabled by default, whereas, Ubuntu Lucid 10.04 has not installed prelink by default
prelink is a utility which modifies shared libraries to relocate faster or in end user's terms, launch applications faster
To enable prelink in ubuntu, we have to install it first
sudo aptitude install prelink
Before running prelink first time, we need to modify its config file to enable prelink on all libraries
To do that, the following editor command will help (if you dont want to undergo the pain of opening a file and editing it)
sudo sed -i s/PRELINKING\=unknown/PRELINKING\=yes/g /etc/default/prelink
To do prelinking on all libraries for the first time, run prelink from cron as follows
sudo /etc/cron.daily/prelink
Now reboot your Ubuntu box, your applications should launch faster like Fedora
awesome tip, thanks! =)

This is why I mentioned "Here may be one of the reasons, it has prelink enabled by default."
ReplyDeleteIt may work, not so sure as Mint 10 is by itself very optimized and based on 10.10. I observed that Ubuntu 10.10 is as fast as Arch and never bother to undergo pain of configuring everything the Arch way
