I wouldn't think threaded searching would help. The operating system knows that many programs read file sequentially, thus, if you read some part of a file from disk, the OS will probably read further if the disk is free, so that the program can access the rest of it faster. (You may even be able to override this behaiviour with the posix_fadvise function.)
