This is a modified rebase of a patch by Tim, see I75f405930a7b14561389c59d147640e870146bec. Some benchmark results (from my laptop): Loading defaults from config-schema.php: - Master: 115/sec ( 8.7ms) - I75f4059: (Tim): 575/sec ( 1.7ms) - Id9dd0bf: (Daniel): 1120/sec ( 0.9ms) - This (Tim+Daniel): 1420/sec ( 0.7ms) Loading defaults and merging settings (worst case): - Master: 80/sec (12.4ms) - I75f4059: (Tim): 93/sec (10.8ms) - Id9dd0bf: (Daniel): 200/sec ( 4.9ms) - This (Tim+Daniel): 682/sec ( 1.5ms) Original commit message by Tim: * Explicitly import function array_key_exists to activate the special opcode * Batch creation of MergeStrategy objects * Batch default assignment to ArrayConfigBuilder The batches mostly help by allowing more inlining, eliminating some function calls. Reduced time for apply/finalize benchmark from 540µs to 170µs. Co-Authored-By: Tim Starling <tstarling@wikimedia.org> Change-Id: I3d4dd685eaaa4351801b3bac6ce1592eea925c5f
