Fedora 11 To Default To the Ext4 File System

ffs writes "The next release of Fedora, 11, will default to the ext4 file system unless serious regressions are seen, as reported by heise online. The LWN story has a few comments extolling the virtues of the file system. Some benchmarks have shown ext4 to be much faster than the current default ext3. Some of the new features that matter for desktop users are a faster file system check, extents support (for efficiently storing large files and reducing fragmentation), multiblock allocation (faster writes), delayed block allocation, journal checksumming (saving against power / hardware failures), and others. The KernelNewbies page has more information on each feature. As is the extfs tradition, mounting a current ext3 filesystem as ext4 will work seamlessly; however, most new features will not be available with the same on-disk format, meaning a fresh format with ext4 or converting the disk layout to ext4 will offer the best experience."

Re:Ext4 small files performance?

I still haven't seen sensible benchmarks for [...] small file read and create

This is pretty hard to benchmark with ext4. You see, those small files are a real lively lot. Trying to get them in one line, then wait for the start signal and then start at the same time has been quite an ordeal.

They've succeeded once, but then the mothers noticed the hustle. You'll be glad you weren't anywhere near. You might not think a lot about a fat mother penguin, which just tells me you have never seen a angry penguin charging at you in excess of 100 mph.
