Flow Latency // Time to Complete Coverage
Latency on Flow is expected to be worse than other chains because, at minimum, 4 calls are required to generate a complete block. Blocks are requested by height, which returns an array of collections by ID. These collections are containers for transactions, thus the collection response (called by individual ID) contains an array of transaction IDs. Transactions are then requested by ID, twice, for the tx body and tx response. The response contains the event data and is often an order of magnitude slower than the other 3 gRPC calls.
