Yoper claims to be a high-performance Linux distribution optimized for newer processors. It incorporates components from other distros, but its packages have been built from scratch to provide enhanced performance. I tested a beta of Yoper 3.0 on my desktop a year ago and was so impressed that when 3.0 was released this month, I installed it on my new Hewlett-Packard Pavilion dv6105 notebook. Using it, however, left me disappointed.
