Well, the main bug, now fixed, was that under -d and use integer, DB::DB was being called for each and every statement. I guess that #14920, Ilya's "autoloaded DESTROY bugfix", was just making DB::DB run a bit slower. Since we're no longer calling DB::DB at all, it's probably irrelevant (to this issue, anyway). Surely any remaining differences are just general 5.6 -> 5.8 slowdown, which we're all familiar with? -- This email is confidential, and now that you have read it you are legally obliged to shoot yourself.
