Benchmarks were conducted using lzbench 2.2.1 (from @inikep), compiled with GCC 12.2.0 using *MOREFLAGS="-march=native"* on Linux 64-bits Debian GNU/Linux 12 (bookworm). The reference hardware is a Google Neoverse-V2 processor (ARM64). All performance metrics reflect single-threaded execution on the standard Silesia Corpus.
