Based on my benchmarks, ISA-l/igzip is more than twice(!) as fast as libdeflate and zlib for decompression. I'm almost enamored with ISA-l because of its speed. And yes, it works on AMD and also has Assembler code for ARM, so probably also works on ARM.
For parallelized decompression of gzip, I recommended my own tool, rapidgzip. I have measured up to 10 GB/s decompression bandwidth with it (>20 GB/s if an index already exists). I'm currently working on integrating ISA-l for even more special cases into rapidgzip and hope to release version 0.9.0 in the next days. It will have another +30-100% performance boost for many cases, thanks to ISA-l.
