-This can be found in the relay chain's runtime. You can see the Polkadot [`async_backing_params`](https://github.com/polkadot-fellows/runtimes/blob/d49a9f33d0ea85ce51c26c84a70b61624ec06901/relay/polkadot/src/genesis_config_presets.rs#L131-L134){target=\_blank} as an example. You also want to make sure that the `lookahead` in [`schedulerParams`](https://paritytech.github.io/polkadot-sdk/master/cumulus_primitives_core/relay_chain/struct.SchedulerParams.html){target=\_blank} is set to `3`. This can be found by querying the [`scheduler_params`](https://paritytech.github.io/polkadot-sdk/master/polkadot_runtime_parachains/configuration/struct.HostConfiguration.html#structfield.scheduler_params){target=\_blank} using the [`configuration.activeConfig()`](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc-polkadot.helixstreet.io#/chainstate) query in Polkadot JS.

 !!! warning 
     The `lookahead` field must be set to 3; otherwise, parachain block times will degrade to worse than with sync backing!
