You're both close :) OCFS2 is based on ext[23], though it has some components that were written specifically for OCFS2. ext3 has htree (dir_index) which addresses most efficiency problems that come from having many files in a directory -- it's not "slow". OCFS2 takes it's directory handling from ext3 but does not include the htree (dir_index) functionality. So almost all operations that involve file names (open, unlink, rename, etc, etc) will see a performance hit in OCFS2 as the number of files in the directory increase. - z _______________________________________________ Ocfs2-users mailing list [email protected] http://oss.oracle.com/mailman/listinfo/ocfs2-users
