Planned improvements include enhancements to jemalloc's hugepage allocator (HPA) mode for better Linux Transparent Hugepage support, increased memory efficiency, and further AArch64 CPU optimizations. Meta has also engaged with the open-source community and jemalloc's founder Jason Evans as part of this renewed stewardship. ## Full article daily.dev links to this article rather than hosting it.
