You mean don't block align files of size less than 1k, and intelligently pack them into the gaps left by files that are aligned? Does seem that most noticeable performance issues occur on sequential reads of large files, this sounds like a good idea, but I would welcome comments on this. Also I assume romfs currently has a small hidden benefit as a result of it storing its file data serially after the inode: the initial read of the inode reads and therefore caches the block containing the (initial) file data. Obviously with block aligned file data this only applies if sequential prefetching is performed. I'd be interested to know if this is an issue worth regarding. -- Lindsay - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
