Certain workloads have a need to have custom performance tuning profiles applied.

For e.g. the IBM Cloud Pak for Data requires various kernel parameters to be set:
(vm.max_map_count) (kernel.msgmax, kernel.msgmnb, kernel.msgmni) (kernel.shmmax, kernel.shmall, and kernel.shmmni) (kernel.sem)

More details can be found here: https://www.ibm.com/support/producthub/icpdata/docs/content/SSQNUZ_latest/cpd/install/node-settings.html
And: https://www.ibm.com/docs/en/cloud-paks/cp-data/3.5.0?topic=tasks-changing-required-node-settings#node-settings__kernel

The settings could be different depending on the underlying architecture, what the default page size is for that architecture, how many threads are available per core etc. For example for IBM Power, the default page size is 64k and the SMT settings could be varied between 1,2,4 and 8. This has an affect on the kernel tunables and other settings.

Currently users have to install OpenShift and post-installation go through a laborious and manual process to prepare the system, before proceeding to Install the workload (Cloud Pak for Data). A custom performance profile per workload, that will allow for variability based on the underlying architecture would ease the burden for the administrators.
