Details queries for a full block are now under 15ms, and for a tx are < 1ms. These compute all fees from raw block/tx data (fees are not cached). Sizes are cached for blocks/txs, because these do not require prevouts. http://localhost/v1/tx/d71ec91f99a5e6865a904a04374a0c64a446bdb55e2df687030c2774495c7d99/details?format=json
