Which filesystem supports journaling as well as faster startup and recovery processes?

The ext4 filesystem is designed to offer several enhancements over its predecessor, ext3, one of which is improved handling of journaling. It supports a more advanced journaling feature that optimizes performance during startup and recovery processes. This is achieved through techniques such as delayed allocation, which helps to minimize fragmentation and boost performance when writing data.

Additionally, ext4 includes features like extents, which allow it to manage larger files more efficiently, and fast fsck (file system check), which contributes to quicker recovery times compared to older filesystems. The combination of these improvements helps ensure that ext4 not only supports journaling effectively but also enhances overall system performance and reduces downtime in the event of a crash or improper shutdown.

While ext3 also supports journaling, it does not have the performance benefits that ext4 provides. The other filesystems listed, xfs and ntfs, offer different benefits tailored to different needs and environments, but ext4's specific improvements in journaling and recovery processes make it the best choice in this context.
