We will probably release a "very beta" not intended for inclusion on the
27th, and ship a patch for inclusion on Halloween before midnight in some
time zone.  In the version we will ship on Sunday, reads are only 50%
faster than ext2/3 for reading the linux kernel source tree.  We have an
old kernel in which reads are 105% faster when reading one copy of the
linux kernel tree.  The delay until Halloween is so that we can figure out
why reads were faster in the old kernel, and hopefully make them 105%
faster in the newest version of the code.

Not sure you want to ship a 3.0 without it.  It is 50-150% faster than V3,
which makes it a significant competitive advantage.  I forget how much
faster writes are, something well over 100% faster, and the newest version
is faster yet.

How do I put it.  I'm the last straggler coming back from the hunt, and
I've got what looks like it might be a wooly mammoth on my shoulders, and
my tribesmen are complaining that I'm late for dinner.  How about helping
me by cutting down a tree for the roasting spit instead?  Think thoughts of
the poor hungry Microsoft tribe eating NTFS.

Think thoughts of Microsoft suits going into some corporate board room
explaining that Windows is worth paying for because of the value add, and
some guy in sandals in the back suggests that the company could replace all
its 15k rpm SCSI hard drives with 5400rpm IDE drives, and Linux would still
be much faster than using NTFS.

Think thoughts of Microsoft's OFS catching up to ext2 at long last (surely
it will, with all the money they have spent to hire people), and then
discovering Windows still offers negative value add filesystem

Oh, and it has features too, not just performance....

ReiserFS ROCKS. I am *so* looking fwd to v4 (but I have to convert all of my 3.5's to v3.6 with ' mount -o conv ' first...)

I sent Hans a list of questions regarding v4 (and a big Thank You for developing Reiserfs); am looking fwd to his reply.
