Warnet + Increase Tx Relay Rate

Warnet + Increase Tx Relay Rate

In order to accurately represent a mainnet environment, it is crucial to consider key components involving transactions and network configuration.

The replication of transaction dynamics is pivotal, emphasizing the need to analyze the effects of varying rates at which transactions are introduced and confirmed within the network. It is beneficial to generate transactions and blocks from different nodes to understand the impact on the network, particularly focusing on the effect of Replace-By-Fee (RBF) transactions, which align with current mainnet behaviors.

Regarding network setup, a close approximation of the actual mainnet is sought, albeit limited by two factors: the inherent obscurity of mainnet's structure and the resource availability provided by warnet. Despite these constraints, meaningful abstractions can be achieved. Tests conducted by @pinheadmz have shown that it is feasible to operate 250 nodes using Docker; with Kubernetes support via warnet, the potential to manage an even larger number of nodes exists. Therefore, there is an ongoing discussion about the optimal number and accessibility of nodes, along with the network topology, to approximate mainnet conditions effectively.

The desired outcomes of setting up such scenarios include identifying key metrics to observe post-implementation. Questions arise regarding the estimation of increased bandwidth and CPU usage in response to changes in relay rate. Moreover, the influence of a heightened relay rate on mempool turnover during peak congestion periods and elevated fee rates is under consideration. Observations on how transaction propagation is affected by different relay rates are also imperative, as well as assessing the memory impact due to variations in internal send queues across peers when relay rates fluctuate.

Feedback is encouraged to refine these ideas further, addressing whether the proposed approach is logical, identifying any gaps, and determining what elements should take precedence in the prioritization process. This collaborative effort seeks to ensure the simulated environment is both representative and insightful for understanding mainnet behavior.
