ansible 2.12 is slower than 2.7

hello everyone,

we upgraded ansible to ansible [core 2.12.1] from ansible 2.7 and now the playbook are executing slower than before.

the same playbook on ansible 2.7 is being completed in less than 5 min, whereas it takes 8-9 min on the newer version,
this is causing timeout on our integration, we can make workaround for this, but just wanted to know any reason for such behaviour or anyone else has this issue.?

we have tried multiple time the same playbook is faster on older version and the latest version is too slow.
can anyone help ?
