- Added '--concurrent-cron-job-syncs' flag for `kube-controller-manager` to set the number of workers for cron job controller. ([#117550](https://github.com/kubernetes/kubernetes/pull/117550), [@borgerli](https://github.com/borgerli))
- Added '--concurrent-job-syncs' flag for `kube-controller-manager` to set the number of job controller workers. ([#117138](https://github.com/kubernetes/kubernetes/pull/117138), [@tosi3k](https://github.com/tosi3k))

- Fixed a data race in the kubelet image manager that can cause static pod workers to silently stop working. ([#88915](https://github.com/kubernetes/kubernetes/pull/88915), [@roycaihw](https://github.com/roycaihw)) [SIG Node]

*   Added the concurrent service sync flag to the Cloud Controller Manager to allow changing the number of workers. (`--concurrent-service-syncs`) ([#55561](https://github.com/kubernetes/kubernetes/pull/55561),[ @jhorwit2](https://github.com/jhorwit2))

- The DownwardAPIHugePages feature is beta.  Users may use the feature if all workers in their cluster are min 1.20 version.  The feature will be enabled by default in all installations in 1.22. ([#99610](https://github.com/kubernetes/kubernetes/pull/99610), [@derekwaynecarr](https://github.com/derekwaynecarr)) [SIG Node]

- Flag `--concurrent-node-syncs` has been added to cloud node controller which defines how many workers in parallel will be initialising and synchronising nodes. ([#113104](https://github.com/kubernetes/kubernetes/pull/113104), [@pawbana](https://github.com/pawbana)) [SIG API Machinery, Cloud Provider and Scalability]

- Added `--concurrent-daemonset-syncs` command line flag to kube-controller-manager. This value sets the number of workers for the daemonset controller. ([#128444](https://github.com/kubernetes/kubernetes/pull/128444), [@tosi3k](https://github.com/tosi3k))

- The `kube-controller-manager` supports `--concurrent-ephemeralvolume-syncs` flag to set the number of ephemeral volume controller workers. ([#102981](https://github.com/kubernetes/kubernetes/pull/102981), [@SataQiu](https://github.com/SataQiu))

- Enabled `kube-controller-manager` to support '--concurrent-horizontal-pod-autoscaler-syncs' flag to set the number of horizontal pod autoscaler controller workers. ([#108501](https://github.com/kubernetes/kubernetes/pull/108501), [@zroubalik](https://github.com/zroubalik))
