One striking difference, however, is when using "yum check-update" to retrieve information on changed packages. The apt-get update command simply retrieves an index file for each package repository, which is fairly fast. Yum, on the other hand, retrieves RPM header information for every installed RPM, which can be very time-consuming. Yum retrieves headers for every non-installed rpm (the headers for the installed rpms are already availible). This is time-consuming the first time the command is run but fairly fast from the second use on.
