Symptoms

ACTUAL BEHAVIOR
---------------
OSB Lazy initialization of DerivedCache causes huge contention that causes latency spikes and throughput drops when load is hit all at once.

The issue is that if load is passed into OSB right after startup, there is huge contention while initializing the DerivedCache (RouterRuntimeCache).

EXPECTED BEHAVIOR
-----------------------
Load is always going to be heavy and we need a way to initialize the DerivedCache BEFORE requests come in.
