NB. Oracle 11g has builtin compression. In general,

I read in another post that with compression enabled,

Hi,

Yes, I agree. That is what I meant when I said The study might be

Hi,
why not starting with lzo first - it`s already in zfs-fuse on linux and it
looks, that it`s just in between lzjb and gzip in terms of performance and
compression ratio.
there needs yet to be demonstrated that it behaves similar on solaris.
Good question and I'm afraid I don't have a

I'm not sure. I would think that most applications are going to use the
POSIX layer where there's no separate API for filetypes.

How? The API to ZFS that most everything uses is the POSIX API.

One thing ZFS is missing is the ability to select which files to compress.
yes.
there is also no filesystem based approach in compressing/decompressing a whole
filesystem. you can have 499gb of data on a 500gb partition - and if you need

nice idea! :)
We plan to start with the development of a fast implementation of a Burrows
Wheeler Transform based algorithm (BWT).

It might be worthwhile to have some sort of adaptive compression whereby

Bellow, follows a proposal for a new opensolaris project. Of course,
this is open to change since I just wrote down some ideas I had months
ago, while researching the topic as a graduate student in Computer
Science, and since I'm not an opensolaris/ZFS expert at all. I would
really appreciate any
