Starting with ext4, there are indeed options to modify the block size using the "-b" option with mke2fs. BTRFS is a modern copy on write file system natively supported by the Linux kernel, implementing features such as snapshots, built-in RAID and self healing via checksums for data and metadata. Reply reply Yes you have miss a lot of points: - btrfs is not integrated in the PMX web interface (for many good reasons ) - btrfs develop path is very slow with less developers compares with zfs (see yourself how many updates do you have in the last year for zfs and for btrfs) - zfs is cross platform (linux, bsd, unix) but btrfs is only running on linux. Dropping performance in case with 4 threads for ext4 is a signal that there still are contention issues. The compression ratio of gzip and zstd is a bit higher while the write speed of lz4 and zstd is a bit higher. Centos7 on host. kwinz. Offizieller Beitrag. Step 6. g. Fourth: besides all the above points, yes, ZFS can have a slightly worse performance depending on these cases, compared to simpler file systems like ext4 or xfs. By far, XFS can handle large data better than any other filesystem on this list and do it reliably too. I don't want people just talking about their theory and different opinions without real measurements in real world. With the noatime option, the access timestamps on the filesystem are not updated.
