snmalloc is a high-performance allocator. snmalloc can be used directly in a project as a header-only C++ library, it can be
LD_PRELOAD
ed on Elf platforms (e.g. Linux, BSD), and there is a crate to use it from Rust.
Its key design features are:
snmalloc's design is particular well suited to the following two difficult scenarios that can be problematic for other allocators:
Both of these can cause massive reductions in performance of other allocators, but do not for snmalloc.
Comprehensive details about snmalloc's design can be found in the accompanying paper, and differences between the paper and the current implementation are described here. Since writing the paper, the performance of snmalloc has improved considerably.
