The first is the average amount of - unused memory in the last block of each file. For example, when the block - size is 512, on average one-half of the last block of each file will remain - unused and the memory is wasted. In contrast, when the block size is 16, the - average unused memory per file is only 8 bytes. However, it requires more - allocations for the same size file and thus more overhead per block for the - dynamic memory management. - - Second, the block size has an impact on the maximum size file that can be - stored in the IMFS. With smaller block size, the maximum file size is - correspondingly smaller. The following shows the maximum file size possible - based on the configured block size: - - * when the block size is 16 bytes, the maximum file size is 1,328 bytes. - - * when the block size is 32 bytes, the maximum file size is 18,656 bytes. - - * when the block size is 64 bytes, the maximum file size is 279,488 bytes. - - * when the block size is 128 bytes, the maximum file size is 4,329,344 bytes. - - * when the block size is 256 bytes, the maximum file size is 68,173,568 bytes. - - * when the block size is 512 bytes, the maximum file size is 1,082,195,456 - bytes. -text: '' -type: interface |
