We can save significant space by combining both sides: so much that we can reduce the WIRE_LEN_LIMIT to something sane again. MCP results from 5 runs, min-max(mean +/- stddev): store_load_msec:34467-36764(35517.8+/-7.7e+02) vsz_kb:2637488 store_rewrite_sec:35.310000-36.580000(35.816+/-0.44) listnodes_sec:1.140000-2.780000(1.596+/-0.6) listchannels_sec:55.390000-58.110000(56.998+/-0.99) routing_sec:30.330000-30.920000(30.642+/-0.19) peer_write_all_sec:50.640000-53.360000(51.822+/-0.91) MCP notable changes from previous patch (>1 stddev): -store_rewrite_sec:34.720000-35.130000(34.94+/-0.14) +store_rewrite_sec:35.310000-36.580000(35.816+/-0.44) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
