Just to announce that last week, I replaced (one by one so no downtime from a rpm builds perspective) the older aarch64 builders we had for cbs.centos.org pool , with newer ones/faster ones.

In the past, we had a mix of ThunderX/ThunderX2 machines, and these were replaced by newer Ampere Altra machines (Thanks to Ampere for having sponsored one machine and Red Hat sponsored the other ones !)

As it was replaced last week, I had a look at some SIGs builds involving aarch64 architectures and compared needed time builds between older platform and newer builders

#kernel / kmod SIG before: https://cbs.centos.org/koji/taskinfo?taskID=3900620 => 30min now: https://cbs.centos.org/koji/taskinfo?taskID=3901748 => 17min

#samba / storage SIG before: https://cbs.centos.org/koji/taskinfo?taskID=3836506 => 59min now: https://cbs.centos.org/koji/taskinfo?taskID=3900306 => 13min

#kernel-automotive / automotive SIG before: https://cbs.centos.org/koji/taskinfo?taskID=3894668 => 41min now: https://cbs.centos.org/koji/taskinfo?taskID=3901722 => 13min

Of course, don't take these metrics as "granted" for your future builds (as it depends on number of other concurrently builds, etc) but at least it should be faster than before (including also for the Image tasks)

I hope that all SIGs building also for aarch64 will enjoy the new aarch64 builders !
