I suggest giving the user the option during an install, if ZFS is supported in that phase. That has a definite benefit, as ZFS only compresses data that makes it to disk after compression is flipped on. Turning on compression after an install is, at least for things like /usr, largely pointless; eventually, as packages get updated etc, more and more of the filesystem will become compressed, but... Point worth noting: it's only of value if the data you have is by and large compressable! If you're a photographer and work with mostly RAW and JPEGs, compression is going to be a waste of CPU cycles and maybe (this is a wild guess) increase CPU cache misses? It'd probably be worth talking to the ZFS developers to find out why compression isn't enabled by default in Solaris/OpenSolaris. They probably had some logic behind it, and it might be relevant. -B -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
