The technique is used to retain allocated memory that contains a data object of a certain type for reuse upon subsequent allocations of objects of the same type. It is used in [[Software:Linux|Linux]] and became the default allocator since 2.6.23.<ref>[https://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a0acd820807680d2ccc4ef3448387fcdbf152c73 Kernel commit that made SLUB the default allocator in 2.6.23]{{Dead link|date=March 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
