Talk:File system fragmentation/to do

Here are some tasks awaiting attention: Article requests : * Section "Why fragmentation occurs" Explain how the efficiency of page cache/buffer cache combined with readahead decreases with fragmentation In proactive techniques, add keeping related files in the same cylinder groups to improve locality of reference, as in Unix File System XFS allocation groups, if they are relevant (see "Scalability in the XFS File System" source) Expand : * Retroactive techniques need improvement. Perhaps algorithms of defragmentation tools?
