- single Now() timestamp for entire stats batch
- optimize number of lookups
- stop building now unnecessary storage pool kind mappings
- remove table/store aggregated stats copying
- collect ExternalBlobsEnabled only on PartitionConfig change
- replace ETxType->CounterId map with absl::flat_hash_map
- remove extra OpType->TxType lookup
- remove call to GetMainTableForIndex for not-index-table shards
