Anaconda takes too much time (a factor of 2 to 4) and too much RAM (a factor of 6 or 7.)
See this Request For Enhancement (RFE) from 2002:
RFE: 2X to 6X faster install via software pipeline and controlled memory footprint
https://bugzilla.redhat.com/show_bug.cgi?id=71184
In the intervening eight years the speed has improved slightly,
while the space has become worse (today: minimum 512MB, usual 1GB.)
The space will always be a problem because we have no swap available
until after partitioning. We have to store both the compressed (125 MB)
and uncompressed (300 MB) initrd.img in the memory. There's X, metacity,
gtk running, kernel itself takes some space and of course lvm (that even
used to lock that 100 MB locale archive in the memory). Plus we need
some margin so the system won't collapse during format when it tiptoes
around your existing logical volumes.
We could have anaconda try to use an existing linux swap partition very
early, but that's for another discussion (and still doesn't help people
who have a fresh machine or Windows)
