| Migrating to Ext4
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.

| But is it faster?
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". |

| Looks to me like the big win is file/filesystem size increases; if you have gynormous files, this may be of interest.
I don't see anything that really touches on performance...

| Delayed allocation, support for extents, and the new online defragger, I expect, will be the biggest areas of performance improvement. 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)

It's so cute that Linux is getting to some of these features now.  |
