[gentoo-user] reiser4 Vs reiserfs for / on new Gentoo isntallation

[Mick]

I know that some of you have been using reiser4 for some years now.
How does it compare in performance and reliability in terms to
reiserfs and xfs?

A few years ago I remember there were problems compiling or running
some applications/libraries on reiser4 - are these problems now over?
Any gotchas?

they don't even come close in performance. XFS sucks with files who are not 
multi megabyte in size.

a loooong time ago there was a bug when compiling kde and without compression. 
Fixed shortly afterwards, never had a problem again.

Thanks Volker for a prompt reply.  Is reiser4 still being developed,
or is Linux now moving towards ext4?

Some googling has shown me that reiser4 gives better performance than
ext4, although not across the board.

linux is moving toward btrfs. ext4 is just a stop gap measure. One that is 
only a good alternative if you don't care about your data.

btw, the one point that kept resier4 out was 'layer violations'. 
Interesstingly btrfs is nothing but a huge 'violation' ...

And yes, Edward is still working on it.

I know what you meant, and I know what Mick meant, but the question is 
nonsensical.

In terms of filesystems, linux does not "move" anywhere. There are too many 
variables, too many options, too many scenarios to consider one fs the 
favoured one.

The correct question is "Is this thing supported?". The answer is that btrfs, 
reiser4 and ext4fs are all supported.

The other question is "Is this things at least somewhat stable?" The answer is 
yes, except for ext4fs, for which I have yet to see a statement from it's devs 
that the on-disk format is not indeed frozen.

I think that on this occasion (new laptop) I will try reiser4 and wave goodbye 
to reiserfs for now.
