Ubuntu tune-up notes
My ubuntu tune-up notes—shell commands; all of them coming from here.
- Bootchart—to understand boot times and delays, if any:
sudo aptitude install bootchart - Clean up after aptitude, which can be a considerable space hog; since installing software leaves a cached copy on disk for future use:
sudo aptitude clean - Cleaning orphans—apt-get can sometimes skim the software database and trim out software that has been orphaned i.e., left without a program that relies on it. Clean up with this:
sudo apt-get autoremove, or this:sudo deborphan - I don’t need localization stuff, so:
sudo aptitude install localepurge - Preload is an adaptive read-ahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times. Install with this shell command:
sudo aptitude install preload - Readahead is yet another daemon like Preload. Install with this shell command:
sudo aptitude install readahead
