I've been using a Linux OS (Ubuntu is my favourite distribution) for a few years now. Let's say 3/4..
I really like it, actually I love it. ;-)
Sometimes though I realize that some software (eg: Firefox) is not as fast as its Windows version.
I've never really known the reason behind it and neither looked for it.
The other day I've found this interesting article about a Linux patch able to boost desktop performance.
It's been tested and afterwards praised by Linus Torvalds himself so I'm looking forward to experience it on my machine...
