Class GameTestsPerformanceIngredientIndex

java.lang.Object

org.cyclops.integrateddynamics.gametest.GameTestsPerformanceIngredientIndex

public class GameTestsPerformanceIngredientIndex
extends Object

Performance benchmarks for IngredientPositionsIndex. These measure the index lookups that storage networks perform on every insertion and extraction. This is not covered by the network tick time benchmarks in GameTestsPerformance, as those do not contain any storage positions. Results are written to runs/gameTestServer/logs/benchmark_results.txt for CI processing.
