The ext3 filesystem does orders of magnitude more I/O than ext4 in mkfs - a brief benchmark showed 14m to make a 1TB ext3 filesystem vs 7 seconds to make a 1TB ext4 filesystem, with the ext3 filesystem doing upwards of 6GB I/O. Since ext4 has been a default in all major Linux distributions for a long time now - RHEL5 has it as default, for instance - there is no reason to default to ext3: users that need ext3 can configure that themselves. So the default now is ext4 for all linux with this commit. Also note that for non-linux and non-windows the default used to be ext3, now it is vfat. Note that there is still support for ext3 as the default if some deployers do choose to keep that as the default, by using either virt_mkfs or default_ephemeral_format configuration option. We are just trying to move the default for everyone who is starting fresh.
