Broadcast stage batches up to 8 entries: https://github.com/solana-labs/solana/blob/79280b304/core/src/broadcast_stage/broadcast_utils.rs#L26-L29 which will be serialized into some number of shreds and chunked into FEC sets of at most 32 shreds each: https://github.com/solana-labs/solana/blob/79280b304/ledger/src/shred.rs#L576-L597 So depending on the size of entries, FEC sets can be small, which may aggravate loss rate. For example 16 FEC sets of 2:2 data/code shreds each have higher loss rate than one 32:32 set. This commit broadcasts data shreds immediately, but also buffers them until it has a batch of 32 data shreds, at which point 32 coding shreds are generated and broadcasted.
