Part of https://github.com/paritytech/polkadot-sdk/issues/4126 we want to safely increase the execute_workers_max_num gradually from chain to chain and assess if there are any negative impacts. This PR performs the necessary plumbing to be able to increase it based on the chain id, it increase the number of execution workers from 2 to 4 on test network but lives kusama and polkadot unchanged until we gather more data. --------- Signed-off-by: Alexandru Gheorghe <alexandru.gheorghe@parity.io>
How to run this collator
First, build Polkadot:
cargo build --release
Then start two validators that will run for the relay chain:
cargo run --release -- -d alice --chain rococo-local --validator --alice --port 50551
cargo run --release -- -d bob --chain rococo-local --validator --bob --port 50552
Next start the collator that will collate for the adder parachain:
cargo run --release -p test-parachain-adder-collator -- --tmp --chain rococo-local --port 50553
The last step is to register the parachain using polkadot-js. The parachain id is
100. The genesis state and the validation code are printed at startup by the collator.
To do this automatically, run scripts/adder-collator.sh.
