Multi-tenancy: SolverFactory.buildSolver is slow when <scoreDrl> usage because KieBase is rebuild every time
Multi-tenant and clustering: high level support
Feature enabled demand system for algorithms that need performance lowering features: timeGradient, constraintMatches, ...
Construction heuristics with 2 planning variables are relatively slow with a high ACC
Multi-threaded incremental Solver (without partitioning): construction heuristics, local search, ...
Time gradient: use demand/supply system for it
