Get a faster CPU or disk? :-)

Seriously, 'svn import' isn't doing the same thing as 'cvs import'.
It's not just blindly copying data into an RCS file. It's compressing
the entire file using a binary-diff algorithm, and then stuffing the
data into database tables. It's just slower.

Someday SVN users might be able to turn off compression, but there's
nothing you can do about it for now.
