@carbonin FYI

The ppc64le runs are still 50-100% slower than the x86 ones. Was this supposed to fix that issue or just make them work?

Basically the same concerns as https://github.com/ManageIQ/manageiq/pull/19689#issuecomment-605289260

[Siddhesh-Ghadi]

There are some improvement in few configurations at travis side which result in slightly better execution time than previous power builds and we are in touch with travis folks to get this sorted.
