Looks like db will be a more efficient way. ;-) Define "database". And explain how any of existing filesystems manages to _not_ qualify your definition. As for "more efficient"... 300 lookups per second is less than an improvement. It's orders of magnitude worse than e.g. ext2; I don't know in which world that would be considered more efficient, but I certainly glad that I don't live there. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
