It's so cute that Linux is getting to some of these features now. ;)
We love you too ;-)

Whether or not that'll fix metadata performance (i.e. what is likely the cause of firephoto's svn up or dpkg's stat "Reading Database..." flood) is unclear. Then again, to be fair, I've not felt any Linux filesystems that handle these cases well other than perhaps reiserfs3 (but that had a SEVERE cost of kernel latency for faster operations)

I don't see anything that really touches on performance...

For me just an 'svn up' or even installing with apt can cause the system to be unresponsive for several seconds with ext3. I suppose that doesn't count though because I'm not running 20 dozen servers that need "tried and true".]]> http://www.dslreports.com/forum/remark,20434264 Mon, 05 May 2008 12:36:49 EDT Migrating to Ext4 http://www.dslreports.com/forum/remark,20433527 SUMware : Thanks to DistroWatch for providing this link.
Interesting read discussing Ext4 features, comparisons, explanations.

Ext4 is the latest in a long line of Linux file systems, and it's likely to be as important and popular as its predecessors. As a Linux system administrator, you should be aware of the advantages, disadvantages, and basic steps for migrating to ext4. This article explains when to adopt ext4, how to adapt traditional file system maintenance tool usage to ext4, and how to get the most out of the file system.
