Majoritatea distribuţiilor sunt foarte bloated. Cel mai enervant este timpul de boot, groaznic de lung la o distribuţie standard. Eu am reuşit să fac o distribuţie custom care să booteze în fix 2 (două) secunde pe un PC Engines ALIX (are CPU la doar 500 MHz). Mai mult durează iniţializarea HDD-ului extern
