In principle I agree, except on one important detail. How can the OS buffer multiple small seek/read operations as effectively as when it is doing a single seek to start-of-file and performing a large sequential read of the entire content? On Unix systems the readahead buffer is continuously increased with logic something like "ok you're still reading sequentially - let me double the readahead buffer when doing the next read". Niel
