Today I performed three installs of a DVD of Fedora 15 rawhide in (mm:ss) to these root filesystems: total type Packages only 21:31 ext2 15:45 22:14 ext3 16:28 21:54 ext4 16:12 The box is a 2.0GHz uniprocessor x86_64, 3.3GB DDR RAM (not DDR2 or DDR3), 4X DVD+RW media in desktop DVD drive ("22X" but only 4X because of media), 7200RPM SATA 3.0 Gbit/s harddrive (138MB/s observed max transfer rate.) I composed the DVD myself using pungi. I excluded all the @Languages by commenting them out in the fedora-rawhide.ks, so the result is 2.6GB instead of 3.5GB. I Fresh Installed the default Graphical Desktop to an existing 16GB partition, reformatted to ext2/3/4. There were 1207 packages which "df" said occupied 3.4GB on the installed root filesystem. Switching to VT2 just before reboot, "ps ax | grep anaconda" showed just over 9 minutes CPU time, for an average 41% CPU utilization. By creating a three-stage pipeline (fetch .rpm and uncompress, %install, %post) and running two pipes in parallel, then the time for package install can be reduced by a factor of 2X or more. Note that there were at least 2*1207 DVD seeks which accounted for about 300 seconds of dead time. One pipeline would recover that 5 minutes easily.
