  27. Balanced trees are more efficient than traditional file system

  29. In general, ReiserFS is as fast as ext2, but is very efficient with
  30. large directories and small files. Additional patches are needed
  31. for NFS and quotas, please see <http://www.namesys.com/> for links.
  32. It is more easily extended to have features currently found in
  33. database and keyword search systems than block allocation based file
  34. systems are. The next version will be so extended, and will support
  35. plugins consistent with our motto ``It takes more than a license to
