39 In general, ReiserFS is as fast as ext2, but is very efficient with
40 large directories and small files. Additional patches are needed
41 for NFS and quotas, please see <http://www.namesys.com/> for links.

43 It is more easily extended to have features currently found in
44 database and keyword search systems than block allocation based file
45 systems are. The next version will be so extended, and will support
