We presently use an old version of the Hoard allocator, which is licensed
under the LGPLv2. Newer versions are GPL or commercial license only, which
is obviously not acceptable.
Benchmarks done by the Lockless group also show that the Hoard allocator
has a very worrying performance dropoff for larger allocations (see
attached image).
[https://github.com/jemalloc/jemalloc jemalloc] ;(not in that graph, but
benchmarked in another graph on the same page) seems to have the best
performance out of all the available options. It originated in FreeBSD
(and is thus under a BSD-style license) but already works on many other
platforms (e.g. the Rust language uses it for memory allocation just about
everywhere, I believe.)
