Disk SpeedUp vs xfs_fsr

Disk SpeedUp is a Windows utility for analyzing and defragmenting drives, as well as optimizing individual files and folders. Its interactive drive map displays fragmentation results. Defragmentation modes can optimize placement for less frequently accessed files or prioritize frequently used ones. Scheduling lets users choose an action, frequency, time, and drives. It can also defragment system files at boot, including page files, registry hives, and hiberfil.sys. The utility offers SSD optimization settings, but its knowledge base says defragmenting SSDs is not recommended because it may reduce their lifespan. Supported file systems are FAT 16/32 and NTFS. Users can exclude files and folders, enable Disk Defrag in the Windows Explorer context menu through Glary Utilities settings, and set the computer to shut down after defragmentation. Glarysoft says the product is designed to avoid damage to drives or stored data and typically responds to technical questions and bug reports within one or two business days. It is listed as freeware at free, with no free trial. The download page lists version 6.0.1.17.

xfs_fsr is a free Linux utility in the xfsprogs project that reorganizes mounted XFS filesystems one file at a time. It copies a target file to temporary storage, then atomically exchanges the data extents of the original and temporary files. With no arguments, it chooses files with the largest extent counts and attempts the top 10% on each pass. A default run lasts up to two hours and records its stopping point for later resumption. You can name filesystems or individual files, with one pass through each target. Targets must be mounted read-write; entries without that option are skipped. Files mapped in memory and files marked no-defrag are not processed. Reorganization needs enough free space to copy the target, with space less fragmented than the original. On quota-enabled systems, the owner also needs sufficient remaining file quota. The manual says system partitions generally do not need this utility and warns that moving bootloader files can prevent booting unless lilo is rerun before reboot.
