After analysis, our cluster used compression, but did not use isal during compression. The compilation of ISAL compress in the current code depends on the macro HAVE_NASM_X64_AVX2. However, the macro HAVE_NASM_X64_AVX2 has been removed, resulting in the compression not using ISAL even if the compressor_zlib_isal parameter is set to true.
