That script does not run 100 copies of date. It runs 100 copies of an empty loop which may well be optimised out of existence.
I'm not saying that Ansible is not the problem, but you do need to start with a fair comparison. Also, your playbook is running 100 times on one system; you may find it is hardly a problem if you run those 100 scripts on 100 remote systems. Regards, K.
