I've just tried, with and without mmap. I am getting similar speeds as before (a sub-second difference one way or the other). mmap is still slower than pre-loading (with -mem=0). That's for the 29M testcase; maybe I should test on something more focused on wordlist performance. BTW, that #if's handling of __MIC__ should probably be simplified - we may write "!__MIC__" alongside "!__ALTIVEC__ && !__ARM_NEON__" rather than inside the AVX-512 sub-expression. Alexander
