Quotes of the week
The kernel is a lazy, deceitful sack of scum; this is the
fundamental principle of virtual memory. It applies in most
situations, some familiar and some surprising, but the rule is that
VMAs record what has been agreed upon, while PTEs reflect what has
actually been done by the lazy kernel.
-- Gustavo
Duartes describes memory management
-- Evgeniy Polyakov claims a slight performance advantage
Unless we uncover devastating issues with the transition from ext3
to ext4 as the default file system, Fedora 11 installed systems
will be using ext4.

Nah, the test shows POHMELFS in-cache performance, so it's probably not really meaningful to compare to NFS, even in async mode: a client crash would likely lose less cached updates with NFS.
But still the graph gave me a good laugh. :) NFS sucks hard in many ways, and it's great to see people working hard on making better networked filesystems (Lustre is nice, I wonder how crfs will be).
