This should reduce the waste of memory on the padding from 128 bytes to 64 bytes on GOARCH=amd64, while preserving bigger padding for platforms with bigger cache line sizes. See https://stackoverflow.com/questions/68320687/why-are-most-cache-line-sizes-designed-to-be-64-byte-instead-of-32-128byte-now Thanks to @tIGO for the hint
