From eebff525b220bf289886062f9af7543292f01124 Mon Sep 17 00:00:00 2001 From: "Claude (Opus)" Date: Fri, 10 Apr 2026 10:27:12 +0000 Subject: [PATCH 1/3] perf(agglayer): selective frontier load/save in bridge-out Replace unconditional load/save of all 32 LET frontier entries with selective operations based on the bit pattern of num_leaves: - load_let_frontier_selective: only loads entries where bit h=1 (entries that will be READ by append_and_update_frontier) - save_let_frontier_selective: only saves entries where bit h=0 (entries that were WRITTEN by append_and_update_frontier) This halves the number of storage map syscalls from 128 to 64 per B2AGG note consumption. Cycle savings vary by frontier occupancy: - Empty tree (0 leaves): 145k -> 116k (-20%) - Populated tree (2^31-1 leaves): 140k -> 60k (-57%) Also adds benchmarks with pre-populated frontier states (2^31 and 2^31-1 leaves) to measure the impact across different access patterns.
