The unhandled.log.gz file for trunk of our main project is 14 Mb and
uncompresses to 233 Mb.  About 90% of it consists of svn:mergeinfo
properties for file that were copied or renamed within the repository;
most of the rest is other random SVN file properties.

With such a huge unhandled.log file, "git svn mkdirs" took about 10s for
me.  I believe that "git svn rebase" should take at least as long, even
if it is a fast-forward.
