Hi, The attached code contains program to estimate the cross-chunk references for ChunkFS file system (idea from Valh). Below are the results:
test on ext3, / partition-1 on 27 March 2007 Number of files = 217806 Number of directories = 24295 Total size = 8193116 KB Total data stored = 7557892 KB Size of block groups = 131072 KB Number of inodes per block group = 16288 Total no. of cross references = 60657 ------------------------------------------------ test on ext3, / partition-1 on 22 March 2007 Number of files = 230615 Number of directories = 24243 Total size = 8193116 KB Total data stored = 7167212 KB Size of block groups = 131072 KB Number of inodes per block group = 16288 Total no. of cross references = 62163 ------------------------------------------------ test on ext3, / partition-2 on 22 March 2007 Number of files = 79509 Number of directories = 6397 Total size = 3076888 KB Total data stored = 1685100 KB Size of block groups = 131072 KB Number of inodes per block group = 16032 Total no. of cross references = 17996 --------------------------------------------------------------------------- test on ext3, /home partition-3 on 20 April 2007 Number of files = 157632 Number of directories = 13652 Total size = 10233404 KB Total data stored = 9490196 KB Size of block groups = 131072 KB Number of inodes per block group = 16224 Total no. of cross references = 27184 --------------------------------------------------------------------------- Comments??
