As suggested above, the bindings are fast:

$ svnadmin create repo
$ svn import -mm ../src file://`pwd`/repo/trunk # import Subversion trunk
$ svn co file://`pwd`/repo wc
$ svn ps -R svn:mime-type foo/bar wc
$ svn ci -mm wc
$ ./x.py repo 2 | wc
   2270 2270 141635

Getting the mime-type for 2270 files takes less than 1 second.

$ cat x.py
import sys
from svn import repos, fs
#t=fs.open_txn(f, sys.argv[2])
t=fs.revision_root(f, int(sys.argv[2]))
for key, val in p.iteritems():
  print key + ":" + str(fs.node_prop(t, key, 'svn:mime-type'))
