For the pitbull machine where I have run such tests, ext4 was faster than xfs for 32 or more threads: up to 8 threads xfs was few percent faster (10% on average). at 16 threads it was a draw (2036 tps vs. 2070 tps). at 32 threads ext4 was 28% faster (2345 tps vs. 1829 tps). at 64 threads ext4 was even 47% faster (2362 tps vs. 1601 tps). Ext4 is a modern release, but it is an update of decades-old technology. It is a journaling file system, meaning it keeps a log or “journal” of changes that are made to a disk. However, Ext4 can be slow at checking a mounted hard disk, and this problem is only exasperated as hard disks continue to increase in size. name: Vivek-Khera: seen: Aug 19, 2013: since: Mar 24, 2005 725 posts: 15 groups: 1 badge: 15 groups [ show more] Ashmash writes "Phoronix has put out a fresh series of benchmarks that show the real world performance of the Ext4 file-system.
