yet, since Btrfs is unfinished. Let's see some examples:

My little few yen in this massacre: Phoronix usually compares apples
with oranges and pigs with candies. So be careful.
Nobody said one should blindly trust Phoronix. ;-) In fact I clearly
said the contrary. I mentioned the famous example of a totally
absurd "benchmark" that used crippled and crashing code from the ZEN
patchset to benchmark Reiser4.
Disclaimer: I use Reiser4
A "Killer FS"™. :-)
I had been using Reiser4 for quite a long time before Hans Reiser
was convicted for the murder of his wife. There was absolutely no
(objective technical) reason to make a change afterwards. :-)
Thankyou, well said!! The 'killer' gag wasn't funny the first time and
it certainly isn't any funnier now. It's in extremely poor taste,
apart from being childish.
As far as speed is concerned, Reiser4 really is a "Killer FS" (in a
very positive sense).
Reiser3 is fast and solid too, I like others have used it happily on
dozens of servers for many years and continue to do so. (At least,
where I can't use ZFS :-X)
It is now maintained by Edward Shishkin, a former Namesys employee.
Who is also sharing his expertise with the btrfs project, a very
positive outcome.

Patches are available for each kernel version. (http://www.kernel.org/pub/linux/kernel/people/edward/reiser4/reiser4-for-2.6/
)
Admittedly, with the advent of Ext4 and Btrfs, Reiser4 is not so
"brilliant" any more. Reiser4 could have been a much larger project
with many features known from today's ZFS/Btrfs (encryption,
compression and perhaps even snapshots and subvolumes), but long
disputes around kernel integration and the events around Hans Reiser
blocked the whole effort and Reiser4 lost its advantage.
