In the upcoming Linux 3.3 is also introduced numerous improvements to the “delayed logging” journal mode for XFS, so that the bottlenecks are eliminated when writing metadata.
XFS is a high performance file system that was developed by SGI, and often on servers, but also for ambitious users is used. The advantages of XFS to be a high in the read and write speed, but also that the file system does not require a check and an on-line augmentation is extremely fast. The weak point of XFS was previously writing metadata, such as occur for example when creating and deleting files. Here was yet hardly XFS on a single CPU also scalable, and these operations were extremely inefficient. Even with optimal settings only half the speed when creating files like ext4 was reached, some operations were 20-50-times slower than with ext4.
