> Hi, > I have a FreeBSD server that has about 10,500 subdirectories within a single > directory. > This number will keep rising and I assume UFS2 has a limit to the number of > sub-directories in a single directory - can anyone tell me what it is? make sure your kernel is compiled with options UFS_DIRHASH or it will be slow the limit is 32765, just because link count is 2 bytes wide and each subdir adds two to base directory. you have to change to 2 level hierarchy. with files - i started creating empty files, it turned slow after about 320000.
