mergify[bot]	2344391c48	indexes nodes' contact infos in crds table (#13553) (#13601) ... In several places in gossip code, the entire crds table is scanned only to filter out nodes' contact infos. Currently on mainnet, crds table is of size ~70k, while there are only ~470 nodes. So the full table scan is inefficient. Instead we may maintain an index of only nodes' contact infos.

mergify[bot]	a536f779ee	scans crds table in parallel for finding old labels (#13073) (#13107) ... From runtime profiles, the majority time of ClusterInfo::handle_purge https://github.com/solana-labs/solana/blob/0776fa05c/core/src/cluster_info.rs#L1605-L1626 is spent scanning crds table finding old labels: https://github.com/solana-labs/solana/blob/0776fa05c/core/src/crds.rs#L175-L197 This can be done in parallel given that gossip thread-pool: https://github.com/solana-labs/solana/blob/0776fa05c/core/src/cluster_info.rs#L1637-L1641 is idle when handle_purge is invoked: https://github.com/solana-labs/solana/blob/0776fa05c/core/src/cluster_info.rs#L1681 (cherry picked from commit 37c8842bcb) Co-authored-by: behzad nouri <behzadnouri@gmail.com>	2020-10-23 15:36:06 +00:00
