Subject: [PATCH] Optimize BatchDelete.size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The change yields a 20% runtime improvement (201µs → 167µs) by caching frequently accessed fields into locals and adding an early-return path when policy is null, which prevents unnecessary work. The key insight is that collapsing repeated object field dereferences (policy, parentPolicy.sendKey) and deferring the call to key.userKey.estimateSize() until the final sendKey decision removes extra virtual reads and method-call overhead on the hot path. The trade-off is a small increase in local variables and a slightly different control-flow shape (an early return) in exchange for lower per-call overhead and no runtime allocations.
